I've only been to Colorado once:
Ski Trip to Colorado in 1999
I went on my first major ski trip in 1999 with some friends and coworkers. We stayed at a condo in Summit County and spent two days at Keystone, one day at Vail, and two days at Copper. I took a full day ski lesson at Keystone and a full day snowboarding lesson at Copper. Snowboarding turned out to be harder than it looked! Three of us had a fabulous meal at the Alpenglow Stube which required us to traverse two gondolas to get to the restaurant at the top of a mountain.
