Kabar,
How does the Grist Mill park on Atlantic Avenue in East Rockaway sound to you?
Also, to me, the photographs look like a scrap yard.
On the line between East Rock' and Oceanside by the marina, there used to be a bit of a junk yard among the boat yards. I remember he had a few cannons stuck between the donkey, goats and chickens. He was across from the Port Hole Bar and I can't remember his name. My B-I-L would. That was ca. 1970.
