Most if of not all campgrounds along the ALCAN will start shutting down mid September so plan for that. Get a copy of Milepost it will provide as a good guide on what to see. Going into Canada is not a problem in ND, just follow the rules posted on the Canada web site for details on what you can not take in to Canada. Have a good trip.
