Memorial Day 2011: Which Ski Resorts will be Open?

I've been compiling a list of ski resorts that are going to be open for Memorial Day (May 28–30, 2011), since I'm hoping to get one last weekend of skiing in this season. I've also been trying to keep track of which lifts, and how much terrain will be open, since I know some resorts like to open token amounts of terrain in order to lure unsuspecting victims visitors. I'll try to keep this up to date as best I can, but some resorts (Whistler Blackcomb) like to change their plans frequently.
