There was a chopper overhead in the area of Woodbridge high school from about 5:00 am - 7:30 am. Moving around some but mostly hovering. Chopper headed west at 7:30 and then I went to work. Oh, and it was a black helo.
How close were you to the helicopter?
Where was the sun in relation to position of the helicopter?
Distance and lighting can make a white painted helicopter look dark gray to almost black.
