I don't have a GPS, but one day about two years ago, I stumbled onto a geocache. It was a decorated, identified geocache made up of an old ammo box. On several different hikes, I went back to the general area where I had found it and re-found it several times.. I dropped odd items into it and logged in on the notebook. This winter the brush will likely be reduced and I may find it again. I'm surprised someone hasn't stolen the box by now, but it seems to hold some respect for those who have found it so far. I think it's pretty cool.
