Fort Allen seemed to be the hardest hit area according to the local TV news reports. Also hit was Hempfield High School (my alma mater) where the roof was torn off of the mini-auditorium and the field house. Fortunately, no one was hurt even though students were participating in after-school activities at the time. Here's a video of it about to hit the school:
Here on the South Side of Pittsburgh, we experienced large marble-sized hail. (I joined half my neighbors on my block rushing to our windows to see what was making all that racket.)
I have to admit that while I'm very happy that no one was hurt at good ol' HASH (Hempfield Area Sr. High as it was called back in the day), I did spend one or more study halls wishing that a twister would spirit me or the whole school off Wizard of Oz-style. On that note, while I was looking for footage on YouTube, I came across the following video. While it's from the Class the year before mine, it gave me a good laugh.
WARNING! This video contains more scenes of feathered hair than is recommended for viewing in a single sitting!
