I especially like the image of the US Capitol I want to say that it's taken from across the reflecting pool... but then the Washington Monument would be in the way... IIRC, isn't there an oval shaped pool in front of the Capitol? I used to live in DC but I haven't been to the Mall since I was probably 12 years old...
Capitol, Grant (and Peace and Garfield?) memorial(s), pond/reflecting pool (complete with ducks), National Mall with Smithsonian buildings of course then the Washington Monument then the reflecting pool then WWII memorial then finally the reflecting pool and Lincoln Monument. (Only know this because I was just there in May and walked from the Capitol to the Lincoln Memorial and back.)
