A visitor to Lake Superior set off on a summer afternoon for a 22-mile voyage from the northeastern tip of Minnesota to rustic Isle Royale and then back again.
On a Jet Ski. Alone.
But fog soon got the best of the 42-year-old adventurer from suburban Washington, D.C., and a massive Great Lakes freighter plucked him and his personal watercraft from the lake nearly 30 miles south of the remote island.
Norma Roth recalled Dave Crevenston calling Grand Portage Marina early in the afternoon on July 8 and explaining his ill-advised plan.
"I told him not to try it," Roth said Wednesday, "And of course, he did it anyway. … He said he had enough gas for at least a round trip."
Roth said Crevenston "was somewhat prepared," wearing a wet suit and packing a life jacket when he departed about 4 p.m.

Roughly seven hours later and well after dark, the captain of the Canadian freighter Michipicoten was alerted by the U.S. Coast Guard about a disoriented personal watercraft user somewhere along the 689-foot ship's intended eastward path.
In an interview Wednesday, Capt. Jonathan Barnes said that Crevenston "managed to lock onto a weak cell signal to call his friend … and passed on his GPS coordinates. "
