Free or Inexpensive Materials

Maps

The following places often provide free maps, although you will probably have to go in person or send a self addressed envelope in order to receive one:

• State tourist agencies and local chambers of commerce publish walking tour maps or guidebooks to area attractions.
• Local government offices, especially those dealing with public transportation, often provide free road maps.
• Car rental companies.

The Federal Government has hundreds of maps available. For a comprehensive listing, contact the Government Printing Office (GPO) bookstore in your area or the Superintendent of Documents, Government Printing Office, Washington, DC 20402.
