Michigan is a U.S. state in the Midwest, surrounded by the Great Lakes. Michigan is divided into two parts: the Upper Peninsula and the Lower Peninsula. The Lower Peninsula juts out of Ohio, while the Upper Peninsula borders Minnesota. Michigan shares a sea border with the Canadian province of Ontario. Michigan and especially Detroit was traditionally the capital of the automobile industry, although it declined in the 1970s and 1980s. Michigan's capital is Lansing, Michigan, while the largest city by far is the aforementioned Detroit.
