I am getting a bit tired of Vail bashing, though. I'm grateful there are people willing to subsidize my skiing. They are the same people that drop money at my client's businesses. I enjoy skiing the VR areas in my neighborhood. The only thing I buy there, besides a very affordable ski pass, is an occasional beer. And that is worth the gouging.
