I totally agree with you re puzzle caches.....I'm puzzled that they are a part of the game.
I think that the magic of geocaching is that it a game where each individual can define what it's about. If you like long hikes in the woods, you have that option; if you prefer numbers, go after P&G's; if you like making things for others, create your own hides; if you like mind games, create and solve puzzles! (The only one I don't get is the impossible challenge caches that clog the landscape, but that's another thread.) As for me, I have enjoyed having every cache in the county logged as a find. Then you have people who hide nanos in the woods and think it's a great cache. I'll get help if I can log the smiley and not have to see the cache on the top of my closest-to-home list reminding me how much I hate that type of cache. (It would bug me to "ignore" a cache.)
