US Capitol!

Mt. Vernon- George Washington's Estate.
We got here late so didn't get to go inside.

9-11Memorial at the Pentagon.  The end of each bench had the
name of a person who died.  If you could read the name while
looking at the Pentagon, the person died in the Pentagon.  If you're back
was to the Pentagon, the person died on the plane, which came from
the direction you were facing.  The benches had water under them,
with a light.  The benches were organized in lines according to the year
the person was born.  The youngest was a 3 year old girl, who was on the plane, and the oldest was a 71 year old man who was in the Pentagon.  Very nice memorial.
BTW- Did you know the Pentagon employs 31,000 people.  28,000 military & 3,000
civilians.  It's the largest office building in the US.
