Query: Much Better Map Books Available

I would give the Perly's people high marks for trying... but that it about all. In terms of currently available map books of the roads and highways of Ontario, this is probably the least helpful and least user-friendly. Ontario map books by other publishers, such as the "Ontario Road Atlas" by MapArt Publishing (issued yearly) and the "Ontario Road & Recreational Atlas" by Whitecap Books are MUCH better in terms of accuracy, detail and features. The MapArt book is excellent for general Ontario travel (it includes backroad names) while the "Ontario Road & Recreational Atlas" has detailed information on parks, trails and conservation areas as well as detailed road maps. Both of these map books are available through Amazon.com as well and I would much reccommend those instead.
