I used to do Turkey Hill Rd. multiple times per week, but usually not the steepest portion of it. I lived in McLean, and would ride to Judd Falls Rd five or six days a week to work at a bike shop there. Great memories. I don't know if they still have the bike path connecting Game Farm Rd. to Judd Falls and State St, but it was a great way to fly in and out of town with no Cornell traffic.
I also tried Buffalo St. once on a fixie. Once.
