  1. I think the whole point of the hint is to maximize the chances of the finder succeeding in finding the cache. You can decrypt or not, as you choose, but the whole reason it's encrypted in the first place is because it is supposed to be a spoiler. Otherwise, it wouldn't need to be encrypted. If reading the hint spoils the fun for you, then don't read it. If you want a challenge in the search (I don't), then don't even think of reading the hint until after you've tried and failed and get so frustrated that you actually want a spoiler.

  2. Even the polar wrap (from Cabelas), helped breathing very cold air, but left your face soaked after a time. Wet face and freezing air not a good mix.

     

    Ah, that's too bad. I guess they still haven't really solved the whole condensation problem.

  3. I was camping in the off season, the cold time of the year, all wrapped up in my minus whatever degree mummy bag, freezing my butt off, and I realized that I wasn't actually losing any significant heat through the bag. It occurred to me that the lungs represent a huge exposed surface area with constant windchill and high humidity, and that surface cannot be covered with a blanket to insulate it from the outside air. If you could protect it from the air you'd die. So, you reach a point where no added layer of clothing is enough to make you warm.

     

    I remember learning about a principle called countercurrent exchange, which has a Wikipedia page. Bacically, by having the outflowing air running in the opposite direction to the inflowing air, intimately close, with a heat-conductive layer between them, you can have an exchange of air with minimal loss of heat.

    It would work best with one tube inside another, or a lot of narrow tubes for the inlet, with the outlet air running along the spaces between the tubes. I did some online searching and found a couple of related patents. They made mention of a serious problem with this application. Although it works well for bringing fresh air into homes, human breath is so humid that such a system would generate enormous amounts of condensation, which, in cold weather, results in clogging the device with ice. Instead of having the two currents run beside each other, the inventors had the air run back and forth along the same path, so that the air did a reuptake of the moisture on the way back in. Then, the whole countercurrent mechanism gets reduced to a simple principle of having a heat sink to grab the heat on the way out and release the heat on the way in, whether that's by passing the air through copper tubing, or weaving copper threads into a face mask. It's counter-intuitive, but it means that, while we normally protect ourselves against heat loss by covering ourselves with non-conductive material, the key to preserving breath heat requires conductive material.

     

    31sfA7SazFL._AA160_.jpg The most common attempt at insulating breath seems to be the balaclava, which amounts to stifling your breath with a cloth. As much as you succeed in getting the breath through the cloth, the heat succeeds in getting out of your body.

     

    41V28MsB7jL._SX425_.jpg The Polarwrap seems to use heat-conductive tubing, as far as I can tell.

     

    31dtE59qvpL._AA160_.jpg Then there's a product aimed at sufferers of COPD, called the Airguard, which seems to be, in a nutshell, an SOS pad (copper fibers) sewn in between layers of fabric.

     

    41ou4JuWeDL._AA160_.jpg The least helpful design I've found is one that traps a cup of stale exhaled air and mixes it into the inhalation. Then, you're stuck with the same problem as the balaclava: the more you succeed in breathing, the more you succeed in losing heat.

     

    It does strike me as interesting how little there is out there in the way of heat exchange masks, considering all the money and material geared toward keeping our outsides warm. It's like washing only half of the car, or painting only half of the room. I'd like to know if anyone has any experience with heat exchange masks, and if there are other products out there that I haven't heard of yet. I haven't bought one of these things, yet, though I'm probably going to try it eventually, if winter ever gets going again.

  4. I don't think the OP will have to worry about anyone talking to them after this:

     

    so get out of my way. starting today, i've got heads to step on. i am about to create a very harsh adversarial environment.

     

    This is Flask you're talking about. She hasn't been any different over the years, and people still like talking to her.

  5. It's a game of psychology. Never place the cache at or in the exact point of interest. It's always safer to make it one-off from the point. You could place it near the cave. When non-cachers see the cave on approach, the cave, itself, becomes the distraction from noticing the cache, and geocachers still get to see the cave when they find the cache.

  6. I only carry micro caches in my back pack so when I find a cool spot I can hide one.

     

    If it's really a cool spot, and if you're really willing to come back to the spot repeatedly for maintenance, then it's worth taking the time to study the location first, then go home and make a suitable cache and return later. If having a cache with you the first time you see a good spot is the only way you'll place one there, then you probably shouldn't place one there.

     

    It's a personal rule that I follow in cache placement:

    Never, ever, place a cache at a location on your first visit. Always come back another day.

  7. :lol: You know, Flask, it drives competitive people crazy when the superstar doesn't give a care about the contest. If a small-timer like me said that, it'd be sour grapes. When the big kid on the block doesn't care for your silly little game, it must really be a silly little game. I'd like to hit a World Series home run and say, "Baseball is such a sissy game."

     

    You may not get off of their leaderboard, but you'll always have to ability to take a swipe at them.

  8. But if they are getting a high percentage of favorite points over a large number of finds wouldn't that suggest that's what the geocaching community enjoys?

     

    Remember these forums do not represent the average geocacher, more the dinosaurs pining for the good old days :)

     

    Dinosaurs have a wider range of experience to draw from. Flies only live a few days, and they think crap is the best food they've ever tasted.

  9. Really? Come on, guys, this is a hobby. Nobody wants to find religious material in their cache.

     

    I do. A person's religion is pivotal to that person's character. Assault their religion and you assault them, personally. I like the people who take the time to visit my caches. If they want to leave something that they feel is important to them, then I'm more than happy to let my cache become a reflection of the people who visit.

     

    Its not religion things that bug me, its the attitude of some people think they got to push their belief everywhere they go.

     

    People will push whatever they think is important. The more important they think it is, the more opportunities they will find or make to "push" those ideas (never mind that no one can actually force you to read the thing. You know what it is when you see it. If you take the trouble to actually read it then it's you're own fault).

     

    This, this is exactly what it is. It's not religion specifically, it's people who see a geocache and say, "Yes, this is the place for me to proselytize."

     

    I just don't understand that outlook. It seems narcissistic. Maybe I'm wrong.

     

    Narcissism is a love of self. This is the love of an idea. When you really love an idea, you'll spread it at any available opportunity.

     

    Like I always say, if you have a pamphlet and you want to leave it, then be my guest. If you see a pamphlet and you want to remove it, then be my guest, but understand that the removal of the pamphlet is just as much a battle of ideas as the placing of the pamphlet. Don't trash somebody's pamphlet and think what a loser he is for pushing his ideas on you, because the act of trashing the pamphlet is every bit the same as pushing your ideas on whoever finds the cache after you.

  10. I'm the bonafide expert on this one. :laughing: They absolutely appeared out of nowhere in early 2010, shortly after the smartphone apps came out. Some may disagree with me, but I will forever hold my ground. Finding a TFTC only log from 2009 or earlier is about as common as finding a disposable camera in a cache for finders to take their picture with (a once common practice).

     

    I defy you :P . This cache was placed in 2007 as a commentary on the use of TFTC-only logs:

     

    Give Me an F!

  11. The cache is not the property of Geocaching.com. They're unlikely to do anything that creates the impression that the physical container is

    something that they control.

     

    I think this statement sums it up nicely. I would add that they don't want to be liable for the bomb scares, the trespassing, the litter, the accidental deaths, etc. They just want to be a listing service. If you put that box on the ground, then it's your box and you're responsible for it. They might decide not to list it, but they won't do anything that suggests a shared responsibility for that physical thing or any damage that results from it (They don't know you, and they just don't trust you that far. No offense :anibad: ).

  12. Gosh. I wonder if anyone has done any studies on the health effects of getting your knickers twisted...

     

    Yes, apparently it's unhealthy to not get your knickers twisted because of the chemicals necessary to make that happen. Feeling sick? :anibad:

     

    Is there a study on the health effects of people who get their knickers twisted about people who get their knickers twisted about cheaters?

  13. And I am tired of dodging hikers, especially those with unleashed dogs!

     

    Excellent! We could solve your problem by banning the bicyclists, and we could throw in a strict enforcement of the leash law to rid me of my second pet peeve.

     

    :P

  14. Personally, I'd rather see a creative hide than an ammo can tethered to a tree trunk. Yeah, I know the ammo cans are great and durable and all...but I rarely see a creatively hidden ammo can.

     

    I'd rather find an ammo box tethered to a tree next to a beautiful waterfall, than the most creatively hidden micro in history in a Home Depot parking lot.

     

    Although I agree with Briansnat's over-all point, neither argument, above, really controls its variables. I would rather find a creatively hidden ammo can in the woods than a creatively hidden micro in the woods. Reasons are as follows:

     

    1) Smaller hides mean more potential crevices and hiding places. In a forest, that's way too easy for the hider and way too hard for the finder.

     

    1a) I hate thinking that I put more effort into finding the thing than the hider put into placing it.

     

    1b) The effort to find it changes from being fun to being a nuisance when the difficulty gets too high. For me, that transition happens on the small end of the small caches, and it includes all micros (in the context of a forest setting).

     

    1c) Overly difficult caches make me feel like a dupe falling for someone else's joke, like going on a snipe hunt.

     

    1d) The more crevices and potential hiding places that must be checked to make a find, the more impact that a finder is going to make on the environment. I mean that aestheticly, not ecologically.

     

    2) :grin: Heck, I just like bigger caches.
