The discipline and practice of planning includes physical design, economic development, and a myriad of other specialties. The American Planning Association (APA) is perhaps the best known organization in the United States, and their website contains some very fine resources for those already in the field as well as for those who would like to join the field. On the site's homepage, visitors can learn about upcoming conferences and workshops, learn about joining the APA, and also read recent news updates about various aspects of planning. While not all of the materials are available to non-members, visitors should definitely look over the APA Advocate, which is their bi-weekly newsletter that addresses legislative and policy issues that directly affect planning. Perhaps one of the best general-purpose areas of the site is the "Your Community" section. Here, visitors can learn about their "Green Communities" initiative, view a set of resources designed to teach children about planning, and read about National Community Planning Month.
