Yes, I have searched, but mostly got a lot of tips about how to stay away from the most crowded lifts on crowded days. I know how to do that, and it doesn't really answer my question about avoiding crowds altogether, to the extent possible.
So here's the deal. I'm going to be in Summit Co. for a non-holiday mid-week in mid-winter. No issue there. HOWEVER, we will be skiing on one Sunday. Any regulars willing to provide a very brief recommendation for 1st and 2nd most likely choices to avoid crowding on a Sunday will be very much appreciated. Loveland is out for a complicated and boring reason, so that leaves A-Basin, Beaver, Vail, Keystone, Copper, and Breck. Minor strategizing tips welcome, but I don't need or want a fifteen point guide on how to keep ahead of the throng; if there's that much of a throng, I'm probably not interested in the strategy. Terrain preference, if it matters, is moderate to bracing (but not hair-raising) off-piste. We like open trees and bumps, but won't be jumping any cliff bands. Ticket price is not a factor because we scored some good ticket deals for later in the week that have given us some wiggle room in that department.
PS: For those tempted to say that Easterners will never find a Rockies hill crowded - a common theme in the posts I found on this topic - take heed that we are used to skiing in Maine, not New Jersey. We were at Vail on a couple of non-holiday weekdays last year, and while it was not truly crowded anywhere on the actual hill (except on the front side in a couple places like Riva and Northwoods), there was enough crowding at some of the lifts and facilities to make me think that the weekend would be pretty ugly.
Thanks in advance.
