So when I lived in MD I was in DC wayyyy to often... The Swedish Embassy is sick. The front door is a waterfall. Go check it out! Also, if your into local theater, DC is definitely one of the hot spots. Some awesome shows are always playing. Im not talking just the classics, I mean freshly written shows that range from the cute to the gawdy. Plus my sister lives there... shes the sh*t.
Do you have to do anything special to visit an embassy? I've always wanted to do that but didn't know how.
My favorite thing about DC is the monuments. It makes me proud to be an American when I visit them. Make sure you see the tomb of the unknown soldier at Arlington. I just got teary eyed thinking about it.
