Having driven many of those highways just last weekend, I consider them to
sufficiently blockaded now, albeit with "normal" DC traffic... ;-)

and one needed prior authorization to enter or leave
the DC area - perhaps mediated by EZ-Pass and a RFID tag on driver
licenses (actually, not very farfetched at all). Since rental vans
were used for prior attacks, they are allowed to travel freely (so
long as they belong to one of the larger rental companies). However,
every subcompact car is suspect, since it can carry a bomb in the
trunk.

Great analogy. I don't understand why people just don't get the
significantly greater threat that ground-based vehicles pose to our
"security". It's idiotic to be concerned about long-shots such as GA when
there is absolutely nothing done to protect against far greater and more
practical means of doing damage.
