I'm the dispatcher at a courier company here in Dayton and have been a delivery driver for many years in the past. Over the course of my carreer I've used many different maps from many different companies covering most regions in the USA. The Engels guide is without question superior to all. The county coverage alone makes it worth the price, but breakdownsof smaller towns in outlying areas and in the case of the Dayton guide, detailed depictions of towns ranging from Sidney to Fairfield and from Greenville to Wilmington make this map indespensible. Zip code areas are clearly demarkated. Even prominent largescale businesses and government agencies within each community are clearly shown-very valuable. I have yet to find an error in terms of road placement. Simply stated, the Engels guide is the best map out there.
Pros: best coverage and graphic detail of any map book I've seen
Cons: finding one to purchase isnt always easy but you can order by phone, and in bulk so thats cool.
