I have played in a few around the city. They just had barrels and wood for bunkers. Big Sky has the sup air. The others don't compare to Big Sky.
Review:
This place was awesome!!! The staff and the refs they have are some of the nicest people you will meet. Barry the owner is a great guy. He fixed my gun up for no charge and will give you lots of tips. I would not recommend going there just after it rained though. It gets a little soggy. If you have never been to Big Sky you should definitely come check it out. You will not be disappointed. One other thing they are cheap to. A case of good paint is $40. Can't beat that. If you can you can bring your own.
