The Rocky Mountain Rollergirls have come a long way since their 2004 debut. The league is now nationally ranked and has a substantial fan base. Of course, they're awesome on skates, but let's give credit where it's due: These girls have a totally killer party bus. The Roller Derby Party Bus leaves the Skylark Lounge, 140 South Broadway, at 5:30 p.m. on bout nights, traveling to Bladium Sports Club for lots of hot girl-on-girl derby action. It leaves Bladium at 9:30 for a 10 p.m. party at Skylark with the Rollergirls. A mere $25 fee includes admission to the bout and a seat on the bus. Oh, and did we mention that the bus has unlimited free beer and Rollergirl hostesses for your drinking and viewing pleasure? Get on the party bus!
