For many years at Appalachian State University, there have been a secret group of ninjas who sneak around doing...ninja stuff. This stuff ranges widely, the most common activity being wearing t-shirt ninja masks and knocking on people's doors at around 2 in the morning. And yes, the guys and girls do go to the opposite gender's floors. And yes, there ARE female ninjas. This tradition carried over from Cone to Hoey when the dorm changed in 2008.
