It didn't finish cooking quite on time, but then, when it came out, there was really no hint of pink not-done-yet, so maybe I was just not using the meat thermometer right. (As for the timing, I expect that was because I kept putting things like casseroles in on the top shelf).
There was much good company, and the food was yummy, and much help in the cleaning up afterwards. And then I listened to people play Order of the Stick (rifmeister stayed quite in character as Vaarsuvius and kept making me giggle) while I napped on the couch. Success!
