Paintball Authority - in VA. Everything there is overpriced and the owners don't appreciate those who aren't frequent visitors. Known to under fill new customers.
Rockwood Paintball - once again, pretty far away, but in VA. Very, very small. However, this allows the owners to get closer to the players. Kind people and very cheap.
Safety: Med-High. I say this only because when you're in a sport in which your objective is to shoot the other team, there are gonna be some risks involved. Splat brothers minimizes these risks. Even the "barbed wire" is made of hard leather. You really don't have anything to worry about here.
Fields: GREAT. If you're looking for great woods ball and superb speed ball, this is the place. The new "Trenches" field has two 3-story towers and one 5-story tower over a huge maze of trenches. If you're in the area, you have to come here, even if trenches is all you play. I can't tell you how much fun that field is.
Prices: Good. I think it's like 15 bucks for a day pass, and their paint is cheap. Most of the time refills are free! :) The rental guns are all 98c's and you can add a flatline for 10 bucks.
Staff: Mostly good. You can't expect everybody to be perfect, but most of the people are nice folks willing to help.
Refs: One or two of these guys are like 13, but they still get the job done. Just don't shoot 'em, okay?
Players: Hard to say. There are a LOT of them. Last time I went the local ROTC was there for practice (Hooah) and I've never met anyone there who holds a grudge.
Conclusion: Awesome. You've gotta come here at least once and when you do, you'll want to come back. Best field I've played. Period.
