I live in MI. My mother was born and raised in the UP, but moved to mid-Michigan for college, marriage, and rest of life.
At times I have been a little nervous when crossing the bridge, especially when it is windy. I remember well the car that went over the side due to wind, because we had crossed within 12 hours of that car going over. There is a windsheer at times, plus the feeling of being so high and sometimes feeling like there is not much support underneath.
It can also be an exhilarating experience, and if you are not driving the view is tremendous.
