Well my official geo-birthday is November 30, 2002. That is when I signed up for my account, but in reality I didn't find my first cache until March 26, 2003. So it has now been 5 years since I started this little hobby.
I'd say I have stayed pretty active that whole time. I've had my ups and downs over the years. There have been a lot of great finds. Lots of rocks, logs, stumps, piles of sticks, trees, bushes, guardrails, benches and lamp post covers. I've seen a lot of geocachers come and go from the game. The rules have changed. The caches have changed...
The first time I went geocaching with my Uncle Duck we found 10 caches... 2 were virtual, 1 micro, 2 would be considered small (that size didn't exist then) and 5 were regular size. This last Sunday we found 32... 2 were regular, 8 were small and 22 were micros. I don't complain about this too much though. I know how to find more challenging caches when I want to.
Overall its been a fun 5 years and I don't see myself stopping anytime soon.
