Coast Guard help joke of the day

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?"
