This year the Cassiar closed while I was on it and I had to double back to the Alaska Highway. I recommend you take the Cassiar on the way up so if it closes, you can take it on the way back instead. That gives you two chances of making it. Buy the Milepost when the 2008 edition is out (it's sold at most gas stations if you wait until you are in Canada). The Milepost lists many of the motels and campgrounds along the way. When you need a motel, call ahead around noon to reserve.
