Imagine a Day at the Beach: Summer in March! This year’s “Summer in March” celebration will be held on Thursday, March 30. Students in Early Childhood through Grade Twelve will enjoy imagining themselves in the tropics for a day of sun, ocean breezes and summer treats. Lower School students look forward to a summer story and a picnic lunch. This is an out of uniform day. Students are encouraged to wear sunglasses and their brightest summer attire. No bathing suits, tank tops, short shorts or other revealing clothing, please.
