Forest Hills Cemetery, Boston, MA
Useful information: The cemetery is open every day from 7:30am until dusk. The site covers 250 acres, and I can easily see taking a lunch and spending the better part of a day there--which I would have enjoyed had the weather been more pleasant--so the fact that there are two public restrooms is a tremendous plus. They're located in each end of the main entrance gate--one women's, one men's. I can't speak for the men's room, but the women's room was quite clean.
