I've been doing some woodsball stuff out in Foxpark. Used to play some of the local stuff in Rock Springs, played a tournament up in Greybull once back in '04.
As far as a club goes, it's going to be difficult. I'd be willing to bet that paintball isn't allowed in city limits, and Vedauwoo is out from like March to October, and it's a $5000 fine if they catch you playing out there. The only possibilities are going out to Two Chicks, playing outlaw out at Foxpark or somewhere else, or finding a place in Denver, Greeley, or Fort Collins. If someone had an airball field, we could probably take that out to Roger Canyon and not have many problems.
I know there are plenty of other players, but I would expect that most of the folks out here are pretty much all woodsball.
I think the best way to try and organize games would be through a Facebook group. If you create one, post here so we can join it.
