Op, is your point that these places are relatively close to DC, yet many DC residents haven't visited and don't know much about them? If so, I don't disagree and am guilty of it. But I will also add that I know virtually nothing about the state of MD other than Montgomery County (eg, don't know how many counties there are in MD, don't know what are the primary industries in the state, don't know much about the state legislature, etc), notwithstanding that I am a MD resident. Pathetic as I write it ...
