Okemo's new trail map has part of the Mountain Rd. closed. The new Green Link takes skiers to the Evergreen lift or Mt. Rd. The bottom of the trail under the Solitude lift is closed. I hadn't noticed that before. Nor had I noticed the new Southface Village trails are closed (to the public). The trail under the lift is open. Perhaps the other trails aren't built. I never skied that area.
