Bo, you need to join some of the club runs in the snowys, especially the annual opening of centenial ridge. Which last year we only made it 4 miles, Mitch, Jason and Will kept going I still don't know how much farther they went. Me, Andy, and Aaron turned back. my wich got a work out that day. I plan on hitting more trail this summer.
There are trails at Vedeuvoo off Happy Jack road. Be warned do not venture off the trails and get caught, fines of up to $25000 can be handed out, manatory federal court and vehicle impoundment. there is mellow trails up there, plus not far from Cheyenne.
