The Glenn is cool track but what makes it cool is the history of auto sport in the area. On any car nut's list should be the Seneca Lodge, driving the road circuit around the town and the International Motor Racing Research Center.
If you don't take your spouse on a tour of the wineries (I like Bully Hill) you will be in trouble.
Aviation enthusiasts should visit: National Soaring Museum, Glenn H. Curtiss Museum and take a sailplane ride at Harris Hill.
Probably the best museum of glass in the country is in nearby Corning.
