Now this is fun for the whole family.
I bought a GPS mostly because it came with Streets and Trips for $140 at Costco. Seemed like a good deal. We used it on a drive to Pittsburg to a friends 40th.
Then Barry tells be about GeoCaching. So I check out GeoCaching.com . We went yesterday.
It was so much fun. If you have a GPS and you havn't tried this I urge you to give it a go.
