Larry and Rachel Ford snapped this photo of a UPS delivery from a horse-drawn wagon while on vacation to Mackinac Island, Michigan, in July 2012. Mackinac Island has a permanent population of 492, although there are thousands more seasonal workers and tourists during the summer months. A unique local ordinance prohibits the use of any motor vehicles on the 3.8-square mile island. The most common means of travel are foot, bicycle, or horseback. Certain exceptions include emergency vehicles, electric wheelchairs for those with disabilities, snowmobiles in winter, and golf carts for on-course use only.
