Safety: The refs are concerned with safty all the time they tell you not to stand next to the entrance to the field until they are ready to go out. Having said that the "DOOR" is a space in the netting that you walk through and are immediatly on a woodsball field.
Fields: There are three fields. Two woodsball and a Castle. One woods ball field is set up so that eacvh side has a high side and a low side. The other is set up so that one side must climb the hill to attack the other. The castle is kind of a loppsided battle in favor of the attackers, they give the attackers two rockets (nerf balls) that if thrown into the center of the fort it kills everyone inside. Very hard for the defenders to win.
Prices: Alright for a day $20
