I suppose that's Sleepy Hollow Cemetery, where Louisa May Alcott is buried (also Thoreau, Emerson, and Hawthorne).
Really, even if you love American literature so much that this would be a genuine pilgrimage for you, it's kind of a lonely vacation to do on your own. I know Ruby's an "autumn enthusiast" but I think it would have been a nicer trip if she'd gone during the summer as part of a tour group. Or even if she'd brought her mother.
Edit: Why on earth does she think a random shot of potato chips on a shelf is interesting content? She's just so odd.
