Stowe and Waitsfield also have great riding, but it is not as easy to put together. The bike shop in Waitsfield has a group ride one evening (Stark Mtn Bikes), and check with Iride in Stowe to see if they do as well. Millstone is close and pretty good. 40+ miles of singletrack. Less climbing, pay to ride, but pretty good, particularly if it stays as wet as it's been.
