I lived in Payson for fifteen years and have driven that road hundreds of times, seeing bikes is rare and for good reason. The sheer volume of drunken idiots traveling up and down that hill is staggering, many towing trailers or boats on a high speed mountain road. Then there are the trucks, tour busses and RV's. Much of the local population are rabidly anti-road bike and make no secret of it. To top that off the shoulders are covered with gravel, sand, glass and debris. There is no chance I would ride past Bush Highway.
