 The mascot is a Quaker, though the original mascot was a badger.
 When the mascot was changed in 2015, there was a good deal of resistance from students concerning the fact that though the school is technically Quaker, very few students are Quaker.
 Students felt misrepresented, the more so since the badger was a mascot the students had chosen themselves, whereas the Quaker was imposed upon them.
 The logo is the historic main building (originally a plantation house and later a Civil War hospital), which is thought by some to be haunted. J.C. Luning
