While riding under the lights at Mountain High West Resort this winter, guests will experience a new form of entertainment. Every evening from 5 to 10 p.m. during the season, Mountain High will produce a spectacular audio/visual display that will include the latest snowboarding videos on a 20-foot high outdoor screen, choreographed laser light shows and DJs pumping out tunes in concert-quality surround sound. Night riding is $30 for a lift ticket ($20 for those between ages 7 and 12), but the entertainment is free.
