My boys always groan when I tell them I used to walk to school (up hill both ways) in -40 degrees in Minnesota as a kid.  But it's the truth.  Of course we wore several layers of clothing.  My breath used to freeze on the scarf wrapped around my face.  Then everyone would get to school and hang up all that wet wool in the "cloak room" and boy would it stink.  Then we would get all dressed up again to walk home for lunch, only to trudge back again for the afternoon session.  Luckily it was only about five blocks to the school from our house. My dad would walk through the alley and across the street to the high school where he taught English.
