I introduced the game to two friends of mine here at my university after reading about the game on slashdot (and spending all summer wondering what I was going to do with my GPS....only wish I had found this sooner). Last Thursday night after class was the first time we could go. We knew we were headed for a forest preserve near Elgin, IL, and it was way, way after hours, but we decided to give it a go anyway. We managed to jam three big guys in an S10 pickup and drive over 30 miles west. We found a place to stash the truck and walked in with a small flashlight. After a really long walk and a lot of backtracking in the pitch black night we got within .01 according to my Garmin 12. Couldn't find it. Then we heard the coyotes. Decided we'd had enough at almost midnight.
We're going to give it another go this weekend. We're hooked.
