Aaahhh...frostbite. Most Winnipeggers have experienced it. All you have to do is forget your toque on a cold day. My experience was my own fault, it was junior high, and I decided not to wear earmuffs (too un-cool!) on a day of -28 C with windchill 1800 W/m^2 (equivalent temp, -38, according to my sources). Very painful. I've had mild frostbite twice since then, once when the temperature was only hovering around the freezing point. I didn't expect to need a toque at 0 C. The wind was ridiculous, though, 70 km/h. So for the next week the skin on my ears was peeling happily. That was just last year.

And in Manitoba we didn't call it sliding, it was tobogganing. In Newfoundland, though, it's sliding.
