IN WASHINGTON DC
This is a place where I used to live and work. The National Mall and Memorial Parks is an official US National Parks unit located in the downtown area of Washington DC.
The National Mall is far from your stereotypical mall and constitutes the entire 250 acre stretch across downtown DC. Within the geographic boundaries of the National Mall lies major historical monuments and landmarks like Capitol Hill, Lincoln Memorial, and the Washington Monument. It is also home to the famous Smithsonian Natural Museum of History and the National Air and Space Museum, among many other incredible museums dedicated to different forms of art and significant events and industries.
Clancy's comment: Yep, have walked for miles around this part of America.
