Insider Secrets for visiting Washington DC

Yesterday was a beautiful day in the Washington DC area and I spent the afternoon indoors watching a play at the Warner Theater. Afterwards as I walked back to the Metro, I couldn't resist taking two quick photos in the bright sun.
The first is of the Post Office Pavillion - our insider secret for getting a birds eye view of Washington. So much better than the Washington Monument because it's free, never a long line, and at the top you have huge windows (instead of tiny, peepholes) and lots of fresh air.

The second is a rare picture of the curved archways leading to the Federal Triangle Metro stop with no people around. I thought it looks majestic and peaceful.
