I also like Skagway much better than Haines. Especially after the ships call all the shoppers back on board for dinner.The roads leading DOWN to these tiny ports are both amazing. You will like the one that isn't foggy, rainy, and cold the best. I also don't think you need to carry gas if you have a range of 150 miles, unless you are venturing beyond the Arctic Circle. Just top off every chance you get......the roadside lodges are usually interesting anyway. You will be hungry for a diversion if you travel the length of the Alcan The Milepost is an 800 page bible of information and ads. Tear out the pages you need for your trip. A copy that is a year or two old is OK, things don't change that quickly......the just move the construction equipment up/down the road a few miles. Barb and Fighter's advice is spot on!!
