We have been doing the PA. to AK. RV trip, about every five years, since 2000. When it comes to remote areas, like much of the Alaskan Highway, it can be difficult to imagine how fast change comes to the area, and how many businesses have failed and are fading into the bush, since our first trip. Nothing wrong with a five year old Milepost, as long you keep in mind that any privately owned road house, campground, bakery, restaurant, tourist trap,fuel stop, motel, etc... may be doing just fine this year, may of closed last season, or maybe it's somebody who paid for an advertisement in the 2014 Milepost, or is listed in that edition, but failed before that edition even printed the first copy.
I have never read official figures, but if anybody had the facts, and stated that a third, or even half, of all businesses in the wilderness of northern BC and the YT have been shuttered in the last two decades, it wouldn't surprise me in the least.
