Query: Poor Quality Product

This book was somewhat enjoyable, until the FIRST time he mentioned that "Daniel Boone's road" through the Cumberland Gap was near Cumberland, Md. In fact, Daniel Boone's road through Cumberland Gap is more than 350 miles from Cumberland, with an entire state (West Virginia) between them. Disappointed, I continued reading until, about 50 pages later, he made the same mistake. Where I'm from, you learn about the Cumberland gap and Daniel Boone prior to 6th grade graduation. How the author, let alone editors, missed this is hard to comprehend. Unless of course one assumes that they wanted to rush a shoddy product to market so that they could make some money as quickly as possible. Then I suppose it makes sense, in a twisted way. I agree that it could use much better maps, and spend more time on the actual building of the canal. But that's background noise compared to glaring, easily discoverable and correctable factual errors.
