The only mail delivery in the country that uses teens and college students who jump back and forth from boats is nearing its 100th summer.
The carriers are hired to jump to piers, hustle to mailboxes on the docks and scurry back to the boat — without falling in.
A never-stopping boat delivers to the 60 or so mansions on Lake Geneva in Walworth County, southern Wisconsin.
The boat can carry about 150 people each morning and runs from mid-June to mid-September.
The U.S. Postal Service pays Gage Marine, which runs Lake Geneva Cruise Line, $1 a year to deliver the mail.
It's been done every summer since 1916. The captain of the boat, Neill Frame, has been doing it for 40 years.
