I've heard a little bit about geocashing and I think it would be a really neat way to get out with the kids and go treasure hunting! I think it'd be fun to learn a little more about the public places in our area as a result.
And the treasure hunting would be really fun... Would be fun to be investigative... Would be neat to find 'em and read the log books to see how many other people are involved...
With Geomate Jr, it sounds like even *I* could find things! Woot!
