RockShar I live in Menominee - the very southern part of the UP. 3 1/2 hours south of Mackinaw and 1 hour north of Green Bay WI. Mackinaw is great. My family tries to get there once everyone couple of years. There is a new waterpark over there but I don't know the name of it. We ususlly stay on theSt. Ignance side of the strait.
