One for you Northeast Ohio riders
Check out Riverview Rd in the Canal towpath area, probably the best scenic twisty road in the area.
Riverview starts at Pleasant Valley Rd in Valley View in the Cuyahoga Valley, between Walton Hills (my hometown) and Parma.
It stretches way down into Akron running through Brecksville and past the Boston Mills ski resort in Peninsula into the historic and slightly haunted Main Street. There's a couple ways one could go from there; Riverview Rd or Akron Peninsula Rd, either route picks up speed as you get near Akron; I suggest coming down on one and heading back on the other.
Also recommended as a family-oriented thing is a ride on the Cuyahoga Valley Scenic Railroad which roughly runs parallel to this route. It'll take you into Main Street and the Hale Farm and Village nearby.
Light speed too slow? Yes, we're gonna have to go right to... ludicrous speed!
