From National Mine to Old M-28 the speed limit is 25mph where it should be 35. It is a trucking route and sparsely populated and has only a couple signs…one each direction in the space of a few miles. It is ridiculous to drive through that area at 25 so people have the natural tendency to go faster….and a ten over ticket is easily the case. Police have a couple hiding spots but can nail a speeder while cruising. That seems to be the common way.
