A guy I know was towing¹ his boat home from a fishing trip to Lake Huron when his car broke down. He didn't have his cell phone with him, but he thought maybe he might be able to raise someone on his marine² radio to call for roadside assistance. He climbed into his boat, clicked on the radio and said, "Mayday, mayday." A Coast Guard officer came on and said, "State your location." "I-75, two miles south of Standish." After a very long pause, the officer asked, "How fast were you going when you reached shore?"
