Look Out for Police
I have not driven on that strech on my motorcycle, but plan on taking it across Michigan this summer on a trip out to Mt. Rushmore. The only advice that I can give and many of my college friends can give is to watch out around those corners for police. Just like deer or skunks, you just never know where they are going to be on the section that runs through Michigan.
I have never done the East side but I have done the West side many times .. I prefere Highway 20 which is north also called the Cascades Highway.
It extreemly good all the way into Montanna
