public transportation will take you just about anywhere worth going to here. A good spot for drinking in DC is the adams morgon area, its just many blocks of bars. Old town alexandria has lots of bars thats pretty damn close to the airport. I could gone on forever about the bars tell me what kind of bar you like than I can be more specific. As far as sight seeing theres the normal monument crap, I guess if you have never been here it might be neat but its beat into the ground for me since I have been here all my life and went to them all on school field trips. As far as good dining old town has many good places as well. As far as places to stay away from dc has to many of those to list.
