None. This is the only indoor field around the central valley that I could think of.
Let me start off by saying this is the BEST FIELD I'VE EVER BEEN TO!! Safety was always enforced, prices was reasonable, rules were also enforced. Staff were always walking around so none of the players equipment would get stolen. Players that weren't playing were reffing which is pretty cool. Nobody cheated. All the players that were there were phenomenal friendly. Pro shop was pretty cool. Staff help you when your having problems with your marker and offered tips on how to play your bunker. By far this is the best field I've ever been to and I just found a permanent place to play paintball.
