Understand a lot of little kids wrestling on smaller mat areas. Can you get 8 big mats for HS in the ExPo. Actually you should be able to do the 5A and 6A on 6 mats. Three was the number of mats per class when they wrestled at the Kansas coliseum. Bet you can get 9 to 12 mats in either the Allen Field House at KU or Bramnlage KSU by not pulling out the lower seats. I think the Missouri State WrestlingTournaments are held at the Mo. U. field house. Could probably host all four classes in either of those places. For all 4 classes I would probably have to go with KSU--to cut travel costs for and missed school days for the 321A schools from way, way out west.
