I am a 37-year-old guy who is involved with a beautiful 30something lady who has a 9-year-old daughter. We try to do things together as a family and in order to keep a 9 year olds attention for any great length of time I have to really make it really cool and interesting. I was into Letterboxing before I found Geocaching, and now that I have a nice GPS, I am into it quite a bit. It is a wholesome family or group thing to do that does not require a TV.
