Many years ago before the days of cell phones and data, a friend, driving home from a fishing trip in northern Michigan with his boat in tow, had engine trouble a few miles inland from Lake Huron. He didn't have a CB radio in his car, so he decided to use his marine radio to get help. Climbing into his boat, he broadcast his call letters and asked for assistance.
A Coast Guard officer responded, "Please give your location."
"I'm on Interstate-75, two miles south of Standish."
The officer paused, "Could you repeat that?"
"I-75, two miles south of Standish."
A longer pause. Then an incredulous voice asked, "How fast were you going when you hit shore?"
