Area 51 Paintball, Mancelona - great field - pro shop on site
TC Paintball, Traverse City - never been there - store is pretty good though
Sorry everybody, but the field is no longer in service. I would explan it here, but you can just go to their website and check it out for yourself. I encourage you to do so. Click on the game schedule link there.
It was a nice field though. Too bad I can't play there anymore.
