I don't have a scanner, but the dogs went off at 3:30 about sirens on 244. Then at 4, helicopter back & forth on Potomac in front of me (so it seemed) 4 times. Got to see the starry sky, but heard someone med-evaced from Chancellors. Any info? Know a lot of people in the area, and the young ones are who I'm afraid were out at 3:00.
