luvwinnie,
We haven't had any extra drills in the Rockefeller Center area lately, but just wanted to say I know how disconcerting it can feel. Sending extra special happy thoughts to wipe away these troublesome ones.
PS - Are you working during the convention? I, and most of my office has put in for vacation then due to reports we've had from directlry from our building management on the subway stoppages and road closures expected during this time.
