Its limited, but Keystone and Copper already have some solid blue terrain open. Copper has its speed course under the Superbee open for the race teams now- parts of that are advanced terrain (especially for someone coming from the mid west) and I would be surprised if that is not open to the public for Thanksgiving.
It'd be nice to have the speed center at Copper open for turkey day, but I doubt it will be. They use the speed course to train and with Ll and Bird of Prey coming up a couple of weeks later, I suspect the race teams will be hitting it hard. They generally don't open the terrain they use for race training to the public until the first weekend of December.
