You think you know everything there is to know about running extemp prep, but every tournament is going to present its own unique challenges.
Today, for example, at the Washington State IE Tournament, I was asked at 7:39 if I could run the extemp room, starting at 8:00. Sure, I said. What I didn't know: the usual location, a lecture hall, was take up by some kind of conference, so all 60-odd extempers and their massive tubs of evidence were crammed into one tiny, echo-y classroom upstairs. Luckily another was available across the hall, so I split 3A and 4A in two, figuring I could monitor both groups pretty easily.
But there still wasn't enough space. One team camped out in the hall for the first round. It wasn't working. Eventually we cleared a third classroom next door, so in all, I'm running three prep rooms at the same time.
I'm amazed it's working.
