Oberlin Film Series
Oberlin Film Series (aka OFS) is an organization that screens movies every weekend in lecture halls. They charge $1 admission.
OFS has meetings every Sunday at 3:00 in Wilder, usually in room 211, where they talk about movies and pick ones to show in the future. They always welcome new members, and if you come to meetings regularly, you can get into all their film screenings for free.
