Missouri doesn't have a mileage rule. Teams may participate in any tournment so long as the tournament is snactioned by NFHS and approved by the state associations.
I was interested to see what kind of competition Collins Hill faces, especially after winning Toshiba easy. Well the 2x Toshiba Champion Collins Hill team just went up to a tournament in Pennsylvania and only took 8th! Canon-McMillan pulled an upset as host and dethroned Central Dauphin as champs. Tournament was Powerade by the way.
