Just finished a 6 week trip through 6 states with the family. We used the Moon books in every other state because they were the best we could find. We (my wife and 8 and 10 year-old kids) thought they all had a lot of information, but were helpful only with pointing out highlights of an area. When it came to finding places, it was lacking in details. They all list restaurants, but only a few in the area. In Montana we were fortunate to find another, much more complete and easy to use book (The Ultimate Montana Atlas). The Moon Montana book went pretty much unread as it never seemed to give us the information we were looking for. Were it the only thing we had to use, it would have sufficed. It is small, which is one advantage, but you will need several other books to supplement it (ie maps, hikes, scenic drives, etc.). You get what you pay for with this book. My advice is to spend a few dollars more and get one that has everything in it.
