I was on a blade-trip with a few friends up at Killington on Jan 3rd and they were spining all of their chairs and with all my years of blading experiance; I can judge the wind speed by how much my blades blow around when I'm riding the chair, and the winds were definately less than 55 mph, that is below the limit for a Poma high-speed quad, and since Killington is much higher than Camelback, the winds at Camelback must have been much lower than that.
