We happened upon our worst nightmare, WE GOT LOST. Yep, there we were in the Hills of Alamo, CA, in a park, lost. We were doing a nighttime only cache named 'Wait Until Dark'. The coordinates listed are for the parking area. After that you follow reflectors to find the cashe. I figured why would I need a GPS so I left it on the dash of the truck. I did take my backpack and the cache description with us (this turned out to be useful later).
Off we went flashlights in hand. Hiked up and down the hills followed the reflectors and found the cache. This was around 10pm. Started hiking back and, you guessed it, we took the wrong trail. (Well, all the trails look the same at night). About 15 minutes into the return trip my friend comments, 'this area doesn't look familiar'. I said 'that is because it is dark and we are going the other way'. When we hit the foot bridge he said it again, 'this area doesn't look familiar, we never crossed a foot bridge on the way up'. At that point he had me convinced since we DID NOT cross a foot bridge on the way up. I saw some lights, through the trees, from the homes below and said there are the houses, let's continue on. We did and then we hit the parking lot, the wrong parking lot. It is now around 10:30pm.
It was at this point that I remembered I had my etrex GPSr in my backpack (I use the Garmin III in the truck and the etrex when I leave the vehicle). I had the cache sheet and therefore the coordinates. I punched in the coordinates and sure enough know I knew where we were in relation to the truck, 3/4 a mile away. The only problem is nothing but dead end streets between here and there.
Finally at 11pm, at the end of yet another court, a car approached. I grabbed my grandson and put him in front of my buddy and I (as people will always stop for a kid). She did, asked us what we were doing after 11pm wondering around in her neighborhood (did I mention these are million dollar homes?). I asked her if she knew what geocaching was. She said no and graciously offerer to drive us to where she thought we parked. She did and we were reunited with our wives. The lady asked my grandson if he learned anything as of a result of this experience and he said, 'yea, geocaching is sure a lot of fun'.
So there you have it, and yes, the cache description does mention to take your GPSr because the reflectors will lead you in but not out. Lesson learned, 'take the GPS with you!'
