There are only handful of places left in the country where mail is delivered by boat.
One of those places is Lake Geneva, Wisconsin.
Photojournalist John Kenney shows us why the mail carriers, hired every summer, must possess speed and accuracy.
Getting ready to go!
The mail-boat itself started in 1916. It carries on a tradition that really goes back to 1873.
You never know when you're going in, and having the crowd there, it really makes it an interesting experience, because when you're running back on the long ones, you can hear 100 people gasping if you're going to make it or not, so it's, it's a cool experience.
Nice! Good style! Nice job, Ryan! We're looking for ability, speed of getting on and off without any problem.
Well you have to be willing just to jump off and jump back on, and it's really scary because the boat seems like it's moving really fast and, I don't know, it's really intimidating!
Oh good, excellent!
It really teaches them good skills that they can carry on the rest of their life and again, they really become actors.
It's theater! It's just a whole show in itself, and I think they all become more outgoing and better quality people having had this job and this opportunity.
Hey, hey! He's got it now!
Nine teenagers tried out, and six made the cut.
The mail tours start this Wednesday and continue until September 15th.
The public is even allowed on the mail boat each morning if they want to watch.
