Besides certain military units, there are lots of people who have some need to push the envelope for whatever crazy reason. One guy who did it more than me tried to cross Canada with some friends. They pulled kayaks thru the snow for a few months, then put their snowshoes in and paddled for a few more months. IIRC, they got about 2/3 of the way across. Then he went to graduate school in biology.

Maybe he was a wimp compared to Shackleton?
