I used to geocache a few years ago, and my favorite items to find were travels bugs. Some were stuffed critters, shells, etc. with a numbered and registered tag. When you found one, you had to move it into anther cache. It was great fun to see where they ended up. One that the kids started ended up Ireland. It was cool. I changed my e-mail a few years back, and I stopped getting updates on the ones we started and moved. For the life of me, I can't reember the names of the ones we were tracking. I'll have to ask me Mum, see if she can recall.
