Almost all of them that are well known like PB Daves, BFG, ect.
This place is simply what paintball fields should all be like. I can't tell you how often you find a decent field but then it's ruined by rude or non caring staff and players. Thats not the case at all here. Mike and Dianne have to be the best around, I used to play at a lot of other fields till I tried Stalker out. Now I only play at Stalker because of how great it is. Like a lot of people have mentioned the pro shop is tiny but complete. They have 4500 or 3000 HPA fills, co2, and just a great display and variety of guns, gear, and the little nick nacks that make it complete. Prices are far better than most places around on gear and paint prices are the best around for quality Blaze paint. This field is the place I take anyone who is interested in paintball or has not played on a pro field before. Everyone ends up buying equipment and comes back to Stalker.
The only cons would have to be the cost of c02 refills, and not enough people around here like to play woods ball. Thats not Stalkers fault though since they have the most amazing woods fields, it's just the players.
