When I drive from Stoneham (MA) to Montreal, I see a gazillion warning
signs that read "BRIDGES FREEZE BEFORE ROAD". By the time you cross the
border those letters are burned into your retina.
North of the border, you get signs with a graphic of a skidding car next
to a graphic of a thermometer registering 0°. I wonder if anyone's ever
driven into a river while working out the pictures?
