I'm thinking U-A and other carriers panicked because most forecasters said the "storm of the century" would whip across the East Coast, thus leaving many a stranded traveler.
With Chicago and other MidWest cities -- understandable.
PHIL: I'm glad you and Sally got to where you were going OK. From experience on NYC highways and even sidewalks any bit of ice can make them dangerous (I have the bruise marks from falling on the sidewalks to prove it.) CATMAN
