RFID: Track My Skiing, Please

DSBPI was in Vail, Colorado this weekend. We'd like to see the following technology implemented for the ski season: RFID tags (maybe, would that work?) embedded in each lift ticket and tied into a virtual trail map of the mountain. At the end of the day, skiers (for a fee) could receive a print-out of every trail they hit. Meanwhile, the mountain operator could get an excellent picture of how the mountain is being utilized -- where the bottlenecks are, where the lift lines are too long, etc. Eventually this info can also be integrated real-time into digital on-mountain displays routing skiers/riders to shorter lines, more powder, etc.
