A July 17 Travel article incorrectly said that Michigan's Mackinac Island is in Lake Michigan. It is in Lake Huron. (Published 7/20/2005)

Fuel costs are enough to make you abandon the car on the side of the road. So do just that. Maroon yourself on an island where vehicles are banned. Several small islands in the United States don't permit cars, making visitors and residents use other modes of transportation, including bicycles, horse-drawn carriages and golf carts.
