I will second what Steamer said above. The Finger Lakes have quickly become one of our favourite spots to vacation and ride.
A ride around Keuka Lake is spectacular, lots of great spots to stop and grab a bite, the Glen Curtis museum is a good way to fill a few hours in an afternoon.
Senaca Lake as Steamer mentioned is also a real nice ride, Watkins Glen is a cool town and again lots of spots to explore.
If you are inclined to travel a bit East Mount Morris is another town to check out, just outside town is Letchworth State Park, lots of great views in the park.
Follow what Steamer wrote and you will have alot of great sights to see.
