For my 51st birthday, I took a weekend trip to Boston on a gravesite photo tour. Early in the morning I visited Cushing's grave to the south in Scituate, and later that afternoon I went to Mount Auburn Cemetery in Cambridge.
Gray's grave, as well the graves of his family, can be found on a slope off the left of the main road.
