Most will probably still be out of town, but Saturday after Thanksgiving up in Pittsburgh is the infamous Dirty Dozen. It's 13 of Pittsburgh's steepest hills, spread over a 55mile ride. It's easy pace between the hills, and sort of a race / survival up them, with regrouping at the top. There's some food provided along the way, so it's a fun day, but quite long.
The hills are no joke, I'd suggest a compact, or even putting smooth tires on a MTB. Here's more info: http://www.dannychew.com/ddinfo.html
