A friend who works at one of the alphabet agencies near DC said this to me on Friday afternoon about transportation along the eastern seaboard: "Do not fly, do not take a train, and (expletive deleted), do not go to New York any time soon." Unfortunately, that's all he would say.
As a side note, it cost the Dems $2.5 million to purchase insurance for their soiree in Boston. At last words, the GOP is foregoing the purchase of insurance for their convention because the risk to insurers is too high and the rates for insuring the event would be astronomical, if not budget busting.
Also the GOP knows buying insurance would be a waste of money, because they can always claim it's the taxpayers' patriotic duty to create a victims fund to provide money for all if anything were to happen.
