Pennsylvania Avenue is certainly among the world's most famous streets.
While the Avenue serves work-a-day Washington as a major east-west transit
route, it is known the world over as the heart of the Nation's Capital.
America's history has marched, paraded, promenaded, and protested its way
up and down the Avenue. The Nation celebrates the election of a president
every four years with a parade on the Avenue, while other national heroes
and foreign leaders have been honored with parades and motorcades there as
well. It is no wonder that Pennsylvania Avenue is called the "Avenue of
the Presidents" and "America's Main Street."
