jcolt... I think the closest league for you guys would be at Headrush in Syracuse, NY (www.headrush.com)
. According to google maps is 2hrs 50 minute drive from Niagra Falls, NY. They have the NYPL which is the New York Paintball League (www.thenypl.com)
. The "main" xball division is full, but they have a 4-man xball lite division which is capped at 10 teams per event, but currently has just 4 or so signed up for the first event which is this weekend. Check out their website for more info on that.
I don't know if there are any fields holding any events in the Buffalo - Rochester area which would be probably less than a 2 hour drive from that area.
would be like a 7+ hour drive. Pennyslvania, Ohio, or Michigan might offer something for you in the 5 hour drive area, you'd have to check on that.
