I was recently in the Buffalo, NY area, and hooked up with a local (Buzz) for a ride in Sprague Brook Park, about half an hour south of the city. The park was nice woodland, with fairly tight singletrack winding through the trees and up and down the gullies, with some stream crossings. No sustained climbs or descents, but a lot of up and down, and a ton of small roots. I had my geared 29er, which was a pretty good setup for the trail, though I only got into high gear a couple of times. Buzz was on a geared 24.
Edit to add: Buzz also wrote up the ride on his “MUni or Bust” blog.
