Moved to NW DC area from rural CO last spring. I've never seen so many hovering helicopters. I've learned from neighbors that whenever the powers-that-be expect a large number of people gathering for any reason, there will be a chopper hanging out overhead. I've used flightaware.com (flightaware [DOT] com/live/airport/DC08) and skycircles (twitter [DOT] com/SkyCirclesDC). Seems like some of them take off and land at hospital heliports.
