They don't open when it is snowing, foggy, or in high winds. It was all 3 on Saturday and I'm not sure about Sunday. All I'm saying is they should use the same standard to open it on weekends as they would on weekdays. I feel like there is a bias towards leaving it closed on weekends, just because it's a weekend. Again, it's supposed to be experts only terrain, not locals only terrain.
Also (and this goes for any ski area), there's really no excuse for being short staffed on a powder day. If thousands of guests can get there, then so can employees.
