Roadside Park Consistency
Michigan has 80+ MDOT-maintained roadside parks, spanning both the Upper and Lower Peninsulas. They are found on state and US highways, and typically are seasonal. Usually found at a scenic natural feature, they can provide parking, outhouses?, and picnic areas. These are not Rest Areas(see USA wiki page).
