My family just started recently. I have owned an eTrex Legend for a couple of years--I like gadgets and there are few gadgets out there with a higher coolness-to-cost ratio than a GPSr. Initially I think I rationalized it as a tool to avoid getting lost or to find alternate ways between work and home when the highway's jammed. Anyway, my mom sent me an article about geocaching from the hometown paper. She wanted to know had I ever heard of such a thing? A few weeks later, we got on a plane to visit her and I brought my eTrex. With nothing better to do one night, I got on the web on my Treo (yep, another gadget) and looked up geocaching.com. I was hooked! I found a couple of local caches, stored them in memory and announced the next morning we'd go out geocaching as a family. Mom, sis, wife, two boys (4 and 1), and me packed into the car and headed out in search of N42 04.487 W87 56.648 "Where's the Hill?" We drove ~ 4 km, parked, and found the cache in about 20 minutes. Nothing special, except a light went on in my head: my wife and kids seemed to have fun, we were outdoors, and I was actually putting my 2 year old investment to good use. A winning combination! I've taken the boys out the last few weekends to find easy local caches--so much easier on my conscience than sitting in front of the TV...
