Michigan is shaped like the palm of a right-handed mitten. At the top of the mitten, above the middle finger, is where the five-mile long Mackinac Bridge connects the lower peninsula of Michigan to the state's upper peninsula.
It's odd that both parts of the state are peninsulas. The lower is bounded by Lakes Michigan and Huron - and the Straits of Mackinac which connects Lakes Michigan and Huron. The upper peninsula is bounded by the Straits and Lakes Michigan and Superior.
Mackinac Island is located east of the Mackinac Bridge in Lake Huron. One of its best known features is that no motor vehicles are permitted on the island. People get around on bicycles and in horse drawn carriages.
There's ferry service every half hour between the island and Mackinac City (lower peninsular) and St. Ignace (upper peninsula). There are three ferry lines, but Shepler's boats have a great water tail that is everyone's favorite.
