Gary/my husband saw the laid off workers today, they protested and to his knowledge have left. If they were there again, tomorrow, the group will be at the museum and hotel, but neither is at Chrysler Headquarters. He felt you have a valid concern, but they protested at world headquarters to show upper management and to make a statement. They were very peaceful at their rally and even took one of their own VT days to do this.
Next the only route around I75 north in Michigan I think is to go to the highway west of it, is it US23? Don't have a map handy. That is a nice road, easy ride, no trucks or pot holes.
