DC Metro is practicing running 8 car trains. As if that is really going to help?
Philadelphia had a parade for the baseball team which drew 2 million on a perfect Fall day - swamped 2 different city subways (the Market Street and Broad Street), the Amtrak train system, the western Suburban train system, the NJ-Philly Patco High Speed train system, the Phila city bus system, the NJ Transit bus system, closed two bridges over the Delaware River .... people were still walking 5+ miles to home or car 4+ hours after the parade ended or went by their location. Many NEVER saw the parade as they didn't get into the city or were stuck intransit.
Have absolutely NO PLANS to be anywhere near DC in the cold winter weather,
JMHO,
