Made it up to Keystone yesterday and the trails are ripping right now. Check out the trail map of the bike park.
The map has good descriptions of the trails, the newest of which is Logger's Way. They describe it as fast and flowy single track. It's wider then single track but very fast and flowy.
While only a blue this trail is very smooth and full of big tables and sweeping burms, definitely my new favorite. Expect to pin it faster then you have in a while.
Most of us are still doing resorts on Sunday, James and friends went up to Vail. So if you wanna ride, hit us up. Somebody will most likely be going to one of the many resorts.
