Schweitzer opened yesterday with VERY limited terrain, as in just the main groomer off Basin Express and the Bunny Hill.
While they only classified the one main groomer as "Open," you could ski anything you could get to at your own risk...or at your skis' own risk.
Anyway, the groomer was nice and not too crowded, but I usually cut over to one of the unopened runs. Anywhere off the main groomer (Midway) was brushy and quite, quite firm by the time I got there. Pic is bottom of Ridge...the open groomer can be seen coming in from behind the trees at center/right-bottom of pic.
But hey, it's still skiing!
