We live right between Rt1 and 113, so am quite familiar with the area, and agree with previous posts re 113. If you want the easiest drive, and don't mind the Rt1 toll, take that until you get to the Rt1 - Rt113 split, and take 113. That will take you right into Maryland, and an easy drive to Chincoteague.
