Lisa Rogak, Stones and Bones of New England

"Swan Point ... famous permanent resident ... H. P. Lovecraft, the horror writer. Fans gather at his grave each year on or around the anniversary of his death - March 15 - to commemorate his work. Attendees say that Lovecraft himself often appears in the form of "something strange" at these gatherings. One year it was a cackle of crows loudly accompanying the spoken tributes, while another year it was an unexpected snow squall."
