The outdoor, if you bring your own stuff, still works out to being pretty close to the same price when you work in the cost of gas. It may end up being a couple bucks cheaper, but not by much. You have to take into account all that is needed to run an indoor facility inside the city limits. Now i'm not going to get into details about everything because I by no means know everything. But people have been paying the $18 for quite some time now, myself included, so clearly it can't be all that bad.

And when you bring your own stuff, the only thing you "need" to use of theirs is the facemask and the ammo. Someone correct me if I'm wrong, but I'm pretty sure thats all I ever use when i'm there.
