The Museum of American History.  What an amazing collection.  Everything from Julia Childs kitchen to the Star Spangled Banner Flag to an original battle ship from the revolution to a statue of George Washington in a toga. 

The Wall.  The Vietnam Memorial wall.  Is amazingly simple and moving!

Lincoln Memorial.  This thing is huge!!!  It really is an amazing memorial.  Just stunning!
