Conventional Wisdom

(Historical Notes: Looking back, I completely cannot remember why I had a whole roll of quarters in my backpack.  I seem to recall it’d been in there for a while before the con, but that only raises more questions.  I SHOULD be wondering why I decided to use all of them to pay my share of the gas money… but I’m afraid I know exactly what I was thinking on that front.  “Hehehehe, this’ll make a funny comic!”)
