Cover art for Crisis lyrics by Alexisonfire

I'm pretty sure that this song is about the North American Blizzard of 1977. It fits in very well, especially the line "your car might be your coffin". nine people were found dead in their cars after the blizzard was over. It was also described as "a wall of white burying the city" there's a lot of other links too. check it out for yourself. http://en.wikipedia.org/wiki/North_American_blizzard_of_1977
