U.S. 45 south of Rockland
Just past Rockland, which is 14 miles south of Ontonagon on Hwy. 45, lies the steepest road decline in the Midwest. During the daytime there is usually a police officer driving up it in her blue state trooper car with a radar to give $105 tickets for going over the posted speed limit of 55 mph. Be careful. My cruise control did not brake and apparently they will not perform on steep declines (although they will do so on steep inclines and moderated declines). In my case I was distracted by listening to an audiobook. Although I am 53 years old and never got a speeding ticket before, I will now invest in a speed alarm and a radar detector for the first time. Both cost less than the ticket.
