Earls Hobby Hangar is closed. As far as getting paintball supplies goes, there's a little shop on main behind the 'scratch and dent mattress' outlet called IT factory or something that fills air and co2 and sells some basic equipment.
There is a woodsball/recball mixture of a field up Logan Canyon across the highway from the Zanavoo restaurant that gets pretty good traffic on weekends in the summers. Otherwise you have to kind of get in with the woodsballers to find out when and where the games are.
If you want to play speedball our field is in Midvale. You can check out the site at www.uxpaintball.com
