Did your lecture hall suddenly drop in temperature? Don't worry, It's probably just a visiting ghost! Anyways...we don't want to keep lecturing you, just remember, there are 10 days left to until the Hallowzine! #UMBCart #Hallowzine #HalloweenCountdown Video description: A ghost comes into a lecture hall and writes "boo!" on a white board that also reads "10 days!". As the ghost appears, the lecture hall grows cold with fog.
