I've scanned the thread and want to add my opinion. I too, like the thrill of finding the container that some one has placed. Reading and signing the log seems important in connecting with the cache, even if I do not exchange trinkets.
I prefer the more difficult or interesting or unique caches. I jumped on the Contact Cache and worked on it until I solved and located it. I've still got the props I used in the solution displayed in my house.
I quit geocaching actively last spring because I became bored with the easy, "go right to it" caches. I've looked to do caches that are in an interesting place or have a uniqueness about them. Check out the "Adrenaline Cache" or the "Shoeless Joe Cache" for some examples.
I placed a cache last spring, but have been somewhat disappointed that few of the strong geocachers in the area have solved it. I made it more difficult, rather than less difficult, and put it in a great location. I was inspired by some of the better caches that I have hunted. Most of those geocachers who have found my cache have commented favorably on it. I agree that the more difficult caches are the least often located. Non-the-less, those are the ones that I prefer to seek.
I will place another cache, but only when I can create a good caching experience for the seekers.
I hope other geocachers will continue to place quality well thoughtout caches.
Just my thoughts.
