As an interesting rt. 31 tidbit: after Port Byron but before rt. 89, you cross the north end of Montezuma. It is the flattest, straightest road I have ever encountered in the finger lakes. There is a bridge at the east end, and a hill at the west, so no matter which way you ride, you have a landmark in front of you that never seems to get closer.

Other tidbit: Canandaigua Lake is the most interesting of them to circle, in my opinion. Least developed, little traffic, and horrendous hills on the south end.
