This is one of several metal photo signs on posts marking the site of "Town Hall." Colonel Charles A. Lindbergh was a frequent guest to Rapidan. Hoover would hold themed weekends during which he would assemble groups of people with like-interests. He was particularly keen on developing air mail so on one weekend he invited Lindbergh and the Postmaster General to discuss the possibility. Hoover's mail was dropped from an airplane on Big Meadow each day he was in camp.
