Below are the directions to Dietz Stadiium. It leaves out the tricky part when coming from Westchester - you can either brave the Tappan Zee or go up 684 to 84 West over the Newburgh-Beacon Bridge, then get onto to 87 up there and follow the directions from exit 19. In either case make sure you leave plentyof time because the Friday afternoon traffic is fierce, though the 684-84 route may give a slightly better shot.
Take New York State Thruway (Rt. 87) North to exit 19 (Kingston). After the toll booth, take the second right on the roundabout onto Washington Avenue. Proceed down Washington Ave. to the third traffic light. Make a right turn at the light and Dietz Stadium will be directly in front of you.
