The Evan's City cemetery located in the prospering city of Evan's City PA is the home of the opening scene of Night of the Living Dead. Not much has changed in 35 years. New residents have been added, some trees are missing from a tornado in the 80s and that is about it. Below are some general shots of the cemetery, some are in Black and White to recreate the effect of the first film.
From what I can tell in the movie, the tombstone to the left is the one where Barbara is kneeling in front of. It is located right at the front of the cemetery.
