My wife and I made the trip last Summer. Took the Alaska ferry from Bellingham Washington to Haines Alaska (a three day trip) then rode thru BC and Yukon to Fairbanks. Spent a day in Denali park and went on around to Tok and home. Whatever you do, don't pass up a chance to fill your tank. Have you gotten a copy of "The Milepost" yet? It's an annual publication about the Alaska Highway that is an essential planning tool.
Don't make the mistake of forgetting that handguns in Canada are a NO NO. When we were crossing into BC from Haines there was a guy ahead of us that thought he could take some pistol parts thru. Not a gun, parts. They turned him back.
