Many people go to see Mackinac Island in the summer because the island passed a local law that says that no one can use a car on the island. Everybody has to ride a horse or a bicycle. In recent years, young people have been using roller skates or roller blades to get around the island. There is a narrow paved road that follows the 8 miles of shoreline. This road is for horses (and their buggies), bicycles, skaters and joggers or just people taking a long walk.
