My two experiences with driving in this area, was, one, to show up at a DC airport on
Monday morning and try to navigate a rental car through DC to the other side of town to a meeting in an obscure building,,,hey, and I have driven in several other countries, Frankfurt, and Paris, etc.....and then, a couple of years ago, after York, I tried to get through the Baltimore/DC area to Virginia that Sat. afternoon. Took forever, at a crawl, for no visible reason! Desperately needs a major multilane Interstate that avoids and bypasses Baltimore and DC south from Pa. (Philly?, Harrisburg?) into Virginia. One stinkin' route is not adequate. Around the east side is probably too populated and congested...around the west side? New raillines cost gazillions and always seem to have to be taxpayer subsidized, and are only workable in high commuter traffic areas, and are of no use to most interstate travelers.
