Iowa is in blocks over 3 days. The finals run all three classes on three mats but the classes run during different sessions up to I believe the semis. Years ago they ran all classes at the same time and it was pretty darn exciting. The problem was there was not enough room for the fans. It grew to big. That's a good problem to have and I believe is a product of having one state tourney. I have to believe we have a venue somewhere at least as large as the barn in Des Moines.
