Is it possible to drive from Seattle, Washington to Fairbanks, Alaska?
Yes. One just uses the Alaskan Marine Highway. Canada permits its' vessels to transit Canadian waters without a Canadian customs and immigration inspection. Now a sailing from Bellingham, WA to Juneau, AK will cost $1,600 one way; this is the price to be able to go to Alaska without being subject to Canadian customs and immigration and the limitations Canada places on Americans wishing to go to Alaska such as firearms limits and possibly being inadmissible to Canada. As with many problems, money can often solve it.
