Which place are the students of Yancey Acedamy visiting for their field trip?

The students were taking a field trip to the Metropolitan Museum of Art.

I could start at any point in my short miserable life to prove it, but things really started going bad last May, when our sixth-grade class took a field trip to Manhattan— twenty-eight mentalcase kids and two teachers on a yellow school bus, heading to the Metropolitan Museum of Art to look at ancient Greek and Roman stuff.
