All-OSCA Pizza Night
A semesterly event where the dining co-ops (or as many as feel like participating) bring their pizza night delicacies to one location and share them with all the other co-ops (or whoever shows up).
[Edit: this is incorrect - KHC does not like that all-OSCA pizza night is held at the same time as Shabbat services and dinner. Due to the rules by which the co-op follows to keep kosher, it is impossible to participate in any all-OSCA event on a Friday night. In addition, services always go to 7pm. KHC's pizza night is held on Sunday so that it does not conflict with anyone's religious practice and thus can be inclusive of those that are religiously observant. -KHC pizza cook & occasional Shabbat service leader (contact w/ questions: firstname.lastname@example.org)].
In the spring of 2007 the official All-OSCA Pizza Night was held at Old B some weekend in May. Harkness unofficially invited Keep and Tank, and a few select friends, to Pizza Night on April 20th. It was a success. Since fall 2007, all-OSCA pizza night has been at either Tank or Pyle Inn.
