Between the 9:15 end and 10:00 beginning of classes, I walked most of the hallways in the engineering buildings. Between the 10:50 ending and 12:00 beginning of classes, along with eating lunch (om nom nom FOOD hungry!), I finished walking all of the hallways of the engineering buildings, plus most of the halls in the connected liberal arts quad complex.
At this rate, I'll have a mental map of the entire campus within a month. Or my knees will have finally broken themselves from all the stairs.
