Yes, there are some historical and geographical inaccuracies in this book, however as a trip guide it is comprehensive and quite helpful. I recently returned from a 6 day trip through the Black Hills, Badlands and Wyoming. The maps were helpful. The restaurant suggestions were excellent. I took several of the Day Trips recommended outside of the area and enjoyed all of them. If you have time check out Spearfish Canyon, Black Hills Wild Horse Sanctuary, Canyon Lake, and Chapel in the Hills. These were true highlights. I carried this book with me every day of my trip and frequently referred to it.
