This has been making the rounds of my friends in the DC area. One of them sent it to me last week. And as a 14-year resident of DC--including 5.5 years in the eponymous Arlington--I can vouch for the heavily commercialised, and blandly uniform nature of the neighborhoods along the Orange Line*. If you travel 3 or 4 blocks off this orange-line-strip you'll find real houses, real neighborhoods, and less superficiality.

for the rap, though. Very creative and spot-on in its satire.
*edited to add the following.
The Orange Line is the Metro subway line that runs from the VA suburbs to the MD suburbs across downtown DC. In Arlington County, the municipal planners decided to maximise high-density mixed-use development along this corridor so you get the profusion of condo blocks, big-name shopping stores, and a clean, fastidious "pedestrian-friendly" environment where everyone still drives everywhere. (Just see the queue of cars trying to get into the Whole Foods parking lot on a Saturday morning for an example of how making a place "pedestrian-friendly" does not equate to more people walking to perform their weekly chores.)
