It's located off Highway 70 in Stone Lake, Wisconsin. I believe the actual road is County BB. Really easy to get to, there's a big sign. No problem.
Overall, this was a very enjoyable experience, thanks in large part to the very hospitable employees. They were helpful, informative, and very nice. The rules were enough to make you feel safe, but not enough to take away the fun of the game. The field was small, but they are expanding. The refereeing wasn't professional, but was effective and relaxed. The ref even blasted death metal over the speakers when we requested it. That allowed us to pwn noobs much more efficiently. The pricing was very fair (20 dollars for rental and a full day of playing), but only field balls were allowed, and they were relatively expensive. It was very fun and probably one of the best paintball experiences I've had. I give them an 8, only because of the size. Other then that, everything was perfect.
