One of my favorite rides is down SR 446 in Monroe and Brown Counties in southern Indiana. Think of the scene of Dave Stoller riding up on the Italian cyclists and getting a pump in his spokes from "Breaking Away." This is a two lane highway that varies from having good broad shoulders to having none with a 45/55 MPH speed limit. However, it is very popular with cyclists who have to deal with cars/trucks towing boats to Lake Monroe, lumber trucks, semis, and trucks hauling limestone. I first rode this in my 20s when most of the road had been improved from a narrow winding rural road. I don't think I ever want to give up riding there.
