George A. Romero recently died in Toronto, ON. He was best-known for his 1968 horror film 'Night of the Living Dead' The film has been designated for preservation by the Library of Congress and it paved the way for five subsequent zombie films plus two re-makes. It should be noted that Romero used the term 'ghoul', not 'zombie'.
Nevertheless, his work led directly to the modern zombie film genre.
In the opening sequence 'Johnny' and 'Barbara' park in front of the chapel, which is clearly visible in the GE view of the cemetery. With the help of film shooting location web-sites I have identified the former site of the farm-house and the bridge.
