The Upper School and Senior Quadrangles, or "Quads," serve as both recreational and study areas for students. The Quads offer an escape from a hectic day if only for a period or two, or the chance to study with friends under a shady tree. On any warm day, students can be found playing games with their friends, studying for a test, or just relaxing with nature. The Upper School Quad contains the Blumberg Outdoor Classroom, a two-tiered brick bench dedicated in May, 1990. Traditionally, the Senior Quad is reserved for the senior class. It serves as an outdoor lounge area with picnic benches and shade trees.
