I have several friends who are stashing and caching in MN. I understand it's not your back yard, but these things spread outward...

Now we just need to get some more stashes located in Wisconsin =) I just started playing this game a little bit. I borrowed a GPS and a friend and I were giving spots for each other to find in the forest reserve that's next to our university. I got a GPS for Christmas, so now it's time to have some serious fun. I'm going to go try the stash that is located in Sheboygan, WI even though according to the comments for it, it's already gone. I still want to find the spot! I've already got a few ideas for spots around the central wisconsin area here, and I'm trying to get some friends convinced to join me in a hunt or two, so hopefully you'll all be able to see a few more stashes pop up in Wisconsin.
