Handheld GPS Unit For GeoCaching

Can somebody explain the excitement of this hobby? To me it seems you have a machine that takes you directly to the cache. I just don't see the fun in it.

You may have a device that takes you to the cache, but most caches aren't obvious. I have found hides in fake rocks, fake cacti, birds, rats, hollow branches, even a small coffin. Also, many caches take you to places you would never have gone to, a great view, a hidden lake, a historical location. And, there is the satisfaction of finding the cache, especially if you have several people looking for it.
If you know of anyone who does it I would recommend going out with them and giving it a try. If it's not for you, no big deal, but there are millions out there that really enjoy it. It adds a little adventure into their lives.
