My biggest issue is my wife doesn't find it fun so most of those are from before marriage or when she's out of town. I look forward to introducing the kid to it later on to possibly have a buddy.
I haven't been geocaching in forever. I used to go all the time, but I saw you post about it in another place and figured I'd join and maybe try to pick up the hobby again
Broke the 200 mark a month ago. Been doing this since last February. Of course the summer was the busiest time for caching since it's just so nice to spend the whole day out.
Geocaching.com would be the site everyone uses, it's free to make an account. Their FAQ is a good place to start as well.
For apps, there is c:geo for Android, Cachly for iOS, or the official Geocaching app for both. I might see about adding more of a wiki or sidebar to this community...
