I just received notice that the free "North to Alaska" guide is now available to be sent to those requesting a copy. In the past it has been a very well done guide. It is a joint publication of the Provinces of Alberta and British Columbia, Yukon Territory and the State of Alaska.
I buy a new Milepost every year, whether I am going to Alaska or not, as I tend to collect them. I have somewhere in the neighborhood of 50+ or - of the editions, going back as far as 1953. 1962 is the earliest one that I bought and personally used to drive to Alaska.
Probably not necessary to buy one yearly,but it doesn't cost that much to have a new one, if you buy one at a discount somewhere. The Church book is also excellent as mentioned above. In the last ten years of trips, I have often bought two copies of the Milepost, one to save and one to cut up and staple, to make it a more manageable size and weight. LOL
www.northtoalaska.com to order the guide or down load it. There is a "clicky" on the page to fill out your mailing information. Of course this seems to place a person on many different mailing lists from interests regarding the north country.
