Well I hope it's okay for a very noob to jump in here and add her shiny new .02
I have a whopping 7 finds, 5 of which I've really enjoyed b/c I found them with my 4 y/o DS. Geocaching for my family and I is something that we've decided to do as a way to spend more time together, get some exercise, see some cool things and places, and ultimately, just have fun at home or when we go camping. I do have a couple of finds by myself from work lunch breaks but those were b/c I'm now hooked on how fun this is and not b/c I care about increasing my numbers. In fact, I doubt my numbers will ever get very big, just b/c I really enjoy caching with my family, and well...a 4 y/o lives and moves in a totally different time continum!
Now IMHO, that's not to say that those GCers who enjoy pushing themselves to get some crazy big number of caches are out of line or playing the game "wrong." I think that just as with any sport, the players all play for different reasons, whether it's the competiton, the comraderie, or whatever. One isn't more right than another--they're each just different, and right for them I guess I just don't understand why there's any reason to complain in this game. At it's most basic premise, isn't it all just about what's fun for you?
