The road
Thunder Lake Road in Manistique, Michigan is graded at 109 corners, about 6.1 for every mile you drive. Nothing on it is truly tight: the sharpest corner still opens to 42 m, so it flows rather than fights. The longest straight runs 1.0 miles, so there is room to breathe between the technical sections.
