Head over to Ski Butternut's Twisted or Scooter Terrain Park and get ready to strut your stuff for the season's first rail jam. Snowboarders and skiers are invited. Just make sure you have a Ski Butternut Terrain Park Pass and a season pass or valid lift ticket. Gear not up to speed? Circle Dec. 27 and Dec. 28 on your ski calendar. Test snowboards via Burton and other reps for free Dec. 27; do the same with skis Dec. 28.
