This map is double-sided and shows the border states and their provincial counterparts, starting with British Columbia and Washington/Idaho/Montana for about 150 miles on either side of the actual border, and carries on eastward through the Prairie/Midwest region, before dipping south to encircle the Great Lakes region, before terminating with New York City at the southern extreme and most of New Brunswick/Maine in the northeast. The purpose of the map is to show the true nature of a region where more than 100,000,000 people live; the highways binding them together, the major cities as insets (Long Island, Boston region, Chicago,Toronto central, Seattle, Vancouver, and Victoria), the many border crossings and the artificiality of the border. This is a map showing how easy it is to travel from North Dakota to Manitoba (for instance), or how easy it is to make a Great Lakes round trip. This map spans a continent and follows the route taken by my ancestor, Alexander Mackenzie, who first crossed the continent in 1793 on foot and mapped the routes followed by all settlers heading westward for the next century, including those Johnny-come-latelies Lewis and Clark, who only followed well-trodden trapping routes made by the Northwest Fur Company traders a generation earlier.
