While visiting my cousin in the Northern Virginia suburbs of DC, we made an excursion to Alexandria. Besides walking the historic streets of the city, we took a tour of Christ Church. The significance of this building is that George Washington was a member of it as was Robert E Lee. You can sit in President Washington's seat which has also supported the butts of the last 20 US presidents (except President Obama as of yet) plus Winston Churchill. Talk about sitting on history!
