Group question: How do the signs and symbols in the Pit change throughout the course of the day?

On September 19, 2007 our group observed the area of campus known as the Pit. Each group member was designated 2-hour long time slots such that we observed the Pit from 10am-9pm. We took photographs of different locations surrounding the Pit such as Lenior and Student Stores to document the activities that occurred throughout the day. Each group member also posted his or her observations concerning the signs and symbols of the Pit.
