I bought this along with several other books on Montana. Its a good resource and has a lot of information, but I found it was hard to use. It was more like a textbook that required me to dig and take notes. While they did provide a few maps, they were sketchy and really didn't help me find where things were located. This is compared to the Montana Roadside Directory which I found to be nicely laid out, and easy to use. I would still recommend the purchase of this if your planning a trip as a supplement to other information. It was my second favorite book of the several I bought.
