Hey man congrats on the move. Both place UXP www.utahxtremepaintball.com
and Paintball Addicts www.pb-addicts.com
are great places to play. Stop in to both and enjoy. The scene slows down a little during the winter ut indoor fields pick up. There are certain "tournament" nights for competitive players to come out and get a deal on paint usually. you might be a little late for getting picked up most teams in the area will let you practice with them. My best advice is to come out and introduce yourself and then play.
Edit: As for outdoor fields there are a few during the Spring/Summer/Fall and there are some things in the works that are great for the Pb community so stay tuned and subscribe to the Utah forum and you will stay in the know.
