IN D.C. FOR SPRING BREAK

Aside from the big, flashing signs on I-83 and I-95, I haven't noticed any special security precautions. I drove across the Key Bridge, through Georgetown to within three blocks from the Executive Office building, then along the northwestern side of the mall, across the Potomac and took the GW Parkway up to the beltway and into Bethesda. I'm certainly not saying that there are no special precautions, just that this casual visitor to downtown DC does not immediately notice them.
