Addresses on 'K' Street are known as a center for numerous think tanks, lobbyists, and advocacy groups. - 

This final note, in which the importance of branding once again becomes clear.

There is, in Washington, D.C., an organization whose job it is to lobby for lobbyists: The American League of Lobbyists.
