Keeping tabs on Diet Coke thefts

Now that I am working at Northwestern for the summer, I feel that it is imperative that I take advantage of the free food that lies often unnoticed in various locations throughout the campus, food for symposiums, conferences, gatherings, etc. 

My special goal is to steal as many cans of diet coke--my favorite beverage--as  I can.

So far I'm at five.

Four from the McCormick Tribune Center (there must be a conference this week), and one from the Block Cinema Moving Picture exhibit opening, though this one was technically not stolen because I volunteer at Block and thus am authorized.
