I ride in a Local Club, the WolfPack. We all ride all different times and normally don't ride with anyone else in town. There's about 35 of us in our group.
Other than that, On Sundays at 1PM at Northwoods Mall, which is about 5 or 10 minutes from CSU.
There's lots of good twistie 2 lane roads back in the "Sticks" if that's what you're looking for.
