Is there a good time in the A.M. to go around D.C. without getting in alot of traffic. We will be leaving on a saturday, towing camper and planning on hitting 495 at 5:30 or 6:30 in the morning, would one time be any better than the other ? We will be going on 95 on the way down and coming home on 81, any advice would be helpfull. Thank you
