DC Ducks is the newest, most exciting way to see Washington. Climb aboard an authentic, fully restored 1942 "Duck" and let the adventure begin! From Union Station you'll waddle down to the mall where you'll see the awe inspiring monuments and fabulous Smithsonian Museums. Then at the Potomac River you'll splash down for a whole different look at the nation's capital. From the land to the water, it's all in the same vehicle!  See the best of Washington, D.C  . . . on land . . . on water!  The tickets are also good in Boston, Key West, St. Augustine, Savannah and San Diego at all Historic Tours of America attractions or tours listed on the passes.
