Paintball Moutain but i find that Paintball Encounters has some more friendly staff and they can help you with any problems.
Paintball Encounters is the best field i have ever played at the staff are amazing the fields and speedball are wonderful and if your having trouble when playing speedball they will give you tips in the middle of the game! (Has happened to me twice). Although with only one speedball field they make up for it by having very good woodsball fields such as junkyard or house. A very good place for beginners to pros they even host some tournys so if you are on a team i hope to see you there!
