My home mountains main lift takes about 12 minutes to get from bottom to top, if it doesn't stop (which it does very often).
I did some math and found this kind of interesting. Say I take 15 runs per day. 15x12=180
180/60 minutes=3 hours.
I'm spending 3 hours on a lift everyday I go skiing. Kinda crazy...
But in all reality I feel like I get closer to 10-13 runs
