When my partner first suggested geocaching to me I was hesitant, because any hobby that requires a decent amount of time and money invested ahead of time should be approached with caution. I like to be careful how I use my money, so it didn't seem like a good idea. However, I found out friends of mine have a GPS and take the kids out geocaching all the time, so why not?
The finding of the cache, seeing what's inside, and trading some of those items for ones we brought was neat. What made it a different kind of walk in the woods for me, though, was the kids. Holding the hand of a three-year-old on a somewhat rocky trail makes you look at the terrain in a very different way. She is completely trusting in your ability to keep her safe from harm as she improves her locomotive skills. It was a new way to experience the world through a child's eyes.
