Shack seems to be the name that follows, lobster, for these place on the piers and docks around Maine. I am sure they are used for other gear and more. This neat green lobster shack is on a pier at low tide in Stonington, Maine on the south end of Deer Island which is at the end of the Blue Hill peninsula. A neat out of the way place. The area houses a large quarry and marble from here dots DC landscape including J. F. Kennedy's Memorial at Arlington.
