well we just have short groomers and an excessive number of snowguns, all we have to do is blow huge piles, spread them out with a cat, and we're done. then it takes a few feet of natural stuff to open up the good mtns and trees and stuff but the east usually opens early weather permitting
i skied on october 30th a few years ago and it was my best ec groomer day of the year, we'd gotten like a random storm up at killy, they spread it out, opened a few lift, and it was banger
