There comes a time in Canada when the roads are impassible!
In the winter it’s often due to the weather . . . snow, ice, sleet, you name it. Usually it’s pretty nasty to be driving long distances during . . . October to . . . uhhh, about May!
In the summer, impassibility is often due to the dreaded road construction! When I used to live in Victoria (on Vancouver Island), and drive back in the summer for holidays, it would be pure torture to be in my non-air conditioned, 1986 Honda Accord, in 30 C weather, on black asphalt , trapped along with the 100 other campers, trailers and semi’s along Highway 3 . . . at a dead standstill while the crews laid more asphalt, or dug out new roads.
