Today's Weather Trivia

30 November

1835: Two military police in a skiff near Kingston, ON, on the lookout for deserters, got entangled in floating ice chunks, in intense cold. The heavy sea kept tossing ice into their boat. One policeman, exhausted from tossing ice back into the water, wrapped himself in sails and lay down beside his companion who was frozen stiff. He eventually crawled to land over the ice, a distance of about 200 m.
