The Sherman Tank was unearthed at Central Islip Psychiatric Center NOT Pilgrim or Edgwood.....I know.....I worked at Pilgrim for 38 yrs......1955 thru 1993. My first nine years were spent with direct patient care....The remaining 29 years I was a member of the Safety Department, Fire and Police, and retired at the rank of Sgt......The " Tank " was not found at Pilgrim / Edgwood .. It was found at Central Islip..and thats a fact...
