Just 15 minutes ago I was walking from the Allen library past Mary Gates and down towards the Fountain when I see this guy with a creepy mask on. He is slim, wearing brown khakis and a black t-shirt. The mask covers most of his face except for his mouth. All he does is look up at buildings and scribble things down in a notebook he's carrying. Why is he wearing a mask? It is orange and ugly and creeps me out!!!! Anyone else seen him? I have a camera phone, but didn't want him to know I wanted to take a pic.
