Free the pizza. In an email to Ezra Stiles students early this morning, Master Stephen Pitti announced that the Morse-Stiles dining hall, with its famous brick-oven pizza, would be open to all students prior to 6:30 p.m. for the rest of the week. The decision to suspend the “no transfers” rule, Pitti said, is in the spirit of building community in light of recent troubling campus events.
