Mike, While you were on the Mackinaw Bridge you should have gone right over to Mackinaw Island. Most transportation on the island is by horse and there's lots of 'poo' to clean up there. Stop by Mackinaw Island some summer day and I'm sure you can clean some up!!
Also while in Michigan there are several Iron Ore factories and I'm sure there's many dirty jobs at these too. Our family loves your show! Keep up the good work! Amy T. - Interlochen, Michigan
