Not only is the Church book more accurate, it is more honest. When you read a campground review in the Church book, you know it was written by Mike or Terri Church. With the Milepost, you have no idea of who wrote the review, perhaps even the business owner. The two publications have different approaches to making a profit. The Church's make their profit off the sale of their books, with no advertising. The Milepost makes their profit from the the sale of the book and the sale of advertising. The same people that sell the advertising, on a commission, are the Field Editors, who also write the reviews. A bit of conflict of interest, IMHO.
Over the years the Milepost has grown from a small travel guide to a bloated guide full of advertising. And the area covered has expanded greatly, I suspect to include more businesses, that might advertise. I have Milepost in my collection dating back to 1953, including the Milepost I purchased on my first driving trip to Alaska in 1962. I tend to buy a new Milepost ever year and the years we are going back, I buy two copies. One I keep original and the other gets cut up and reduced to more of a manageable size. A straight edge, razor blade, a stapler and a hi-lighter pen will fix sections for me.
Another fine source of northern information are the many publications put out by the Bell Publishing Group. Available at most Canadian and Alaska visitors center. Tim Bell, grew up on the Alaska Hwy in a road house owned by his family. First class work the Bell family does on their individual maps and articles. Most of their work is free at the centers, in the wall racks.
Another fine book is one writen by Ron Dalby, a retired helicopter pilot that lives in Palmer. The author is a superb writer, but needs to go back over his Alaska Hwy book and bring it up tu date. The last time it was up dated it had way too much incorrect information in it. Appeared that the publisher just put a new date in the front and called it updated. If Dalby would drive the highway with his book in hand, correcting names, etc. and republish it, he just might have the premier Alaska Hey Travel guide of all.
I carry 8 or 10 books/guides with me on our trips to the north country, one on fishing the highway streams and lakes, etc. Redundancy is good, in my view. Also like the Frommer's books, the Dummies ones. Have bought a few that weren't worth killing a tree for the need paper to write them.
I think Terri Church also lived in Nenana, my last home town in Alaska, as her dad was the station master for the Alaska Railroad there.
