I agree - that's the only reason I didn't include, for example, downtown DC, Dupont Circle, etc. Those are great neighborhoods but unfortunately would probably be an hour+ drive to Laurel, with the bulk of that time spent getting from the middle of the city onto the highway. So I tried to limit it to "urban" areas that were very close to a highway which would get to Laurel easily, and were on the east side of the area (e.g. Bethesda is close to the Beltway, but I would not wish a twice-daily drive across Montgomery County on the Beltway on my worst enemy)
