My family and I are planning to take a road trip (starting from Milwaukee) up along Lake Michigan to Northern Wisconsin and then crossing the Mackinaw Bridge to get to Michigan and come back down the other side of the lake. Just wondering if anyone has any suggestions for cool/interesting places for us to stop in Michigan or Northern Wisconsin? We don't have any little kids with us so we don't necessarily need "family fun," but my mother can't walk very well so if there are any pretty landmarks or parks to stop at they need to be accessible for her, so no big hills or steep staircases to climb up. Other than that I'm curious and open to people's suggestions :)
