Your local AAA branch is one source for obtaining physical maps in the United States. Although most people use digital maps these days, AAA members receive free state, county and local maps on request -- including nearby towns.
AAA -- formerly known as the American Automobile Association -- has branches in every major city in North America. In addition to providing the maps, they can help you plan a route for a road trip and provide other travel-related services. In addition to towns and cities, AAA also provides maps for National Parks and other tourist destinations. Members can also order maps online.
