Grover’s Mill, New Jersey! January 7, 2014January 2, 2014 The marker is bigger than I thought! Grover’s Mill! Yeah, I went there, 75 years later. There’s a park and a plaque, and signs along a path with background info about Orson Welles and the panic broadcast of 1938, all on the exact spot where the Martians were said to have landed! Grovers Pond is adjacent.
