Maybe you’re in Michigan, with family in Wisconsin (or vice versa). Or perhaps you’re planning some sort of trip across state lines, and you came across the idea of using a ferry to save some time around the Great Lakes.

MIAMI BEACH, Fla. – The bodies of two women were discovered in a car that rolled off a ferry into a deep shipping channel off the coast of South Florida. Their family members were notified of the deaths, the Coast Guard said on Twitter. Miami-Dade police identified the women as Emma Afra, 63, of Miami, and Viviane Brahms, 76, of Harrison, New York. The Coast Guard is investigating how the car fell from the ferry, which takes people and cars back and forth from the exclusive Fisher Island. The front and back of the ferry are usually closed by chains during the short trip.
