Not a whole lot of context to add for this one.  I went out to change out of the Dr. F costume, and wound up staying out there for a good long while ‘cos I was scared to get out of the car.  I couldn’t tell what any of these folks were actually mad about, but they stayed mad about it for a loooooong time.  I finally darted back out to the con when it sounded like they’d quieted down, but when I came back to drive home a few hours later THEY WERE STILL THERE SCREAMING AT EACH OTHER.  Winston-Salem is an angry place.
