Not knowing how long it would take to get from one stop to the next and hearing all the horror stories of travel in Canada on the Alaskan Highway, I planed not to drive more than 4 hours a day. Also not knowing how much daylight there would be at that time of year, the 4 hours seemed about right. One stop I got to in 2 hours and decided to go on too the following stop. Needless to say, that is when we ran into a snowstorm and almost didn't make it to that next stop and I was kicking myself all the way for about the last few hours. We didn't get to that next stop until after midnight. The other thing I found out is that at that time of year, there is little traffic on the highway between those out of the way towns.
The Alaskan Highway Mile Post book was the best thing I ever did. It told what to expect at each mile post and what to see in between.
