Need any and all ideas for things to see and do in Michigan

Of course, you will want to do Mackinac. Stay at the Mill creek campground near Mackinaw City. There is a great state historical park within bicycling distance that has a working water driven saw mill. Really cool! Colonial Michilimackinac, Old Mackinac Point Lighthouse, And yes, you will want to plan on going to the Island, also.

Find a local restaurant that serves Pasties. They are something everyone must try while there.
