The lost highway
Dogs use their keen sense of smell, birds track Earth's magnetic fields, and we take a highly detailed map and stare at it with blind panic. If you need to bone up on your cartographic competence, be it for a trip across town or across the country, we'll help you get where you want to go.
Before you begin
For this 2torial, you'll need a local map and a U.S. road atlas, which will include a national map as well as more detailed maps for each state (and most major cities), arranged alphabetically. Both should be available at your local gas station, supermarket, or bookstore. Be sure the maps are current (less than five years old) to ensure accuracy. Streets and highways can change names and sometimes disappear entirely, while new construction pops up every day.
