I know where the camp was at Pass Christian. Highway 90 at Menge Avenue. Later moved up Menge past Johnson's Bayou near the Dixie White House Nursing Home. There were also watch sites at Henderson Point. Camps Clark and Lovell were north of the Bay St. Louis bridge near the yacht club and further up at Cedar Point near the mouth of Jourdan River.
The site near the mouth of the Pearl River is a different story. I wish I knew where that outpost was located.
