Welcome from Tavistock, UK!
I spent a couple of weeks in DC back in 1987 and really enjoyed it - so many things to do and see. My introduction to the place the day after I arrived was to go and see the Kevin Costner film 'No Way Out', which is set there and had just been released. It was quite an education - instead of an over-priced miniscule tub of ice cream that we'd have in a British cinema we did it the American way with a bucket of popcorn and a vat of Coke!
