Per the Grable book at CAHS, Inc., the Sampson Speedway was located on what was the original Nicholas Platter patent land, "Bound Brook", located across Sugar Camp Run of Pigeon Creek, from the original patent of Abraham Hickman and Vincent Colvin, both sitting with land to the south and at the junction of Pigeon Creek and Sugar Camp Run. Appears to be north of Capt. James B. Gibson lands were located also.
