Oklahoma is not a USA wrestling state. You don't need a USA card to wrestle in the state series in OK. In January they could/should have found out about the state series in OK and wrestled there. The USA card does not grant you any rights to a state qualifying tournament. My son bought his USA card in MO for the last several years. We were not allowed to, nor should we have been allowed to wrestle in MO state series even though that is where our club was and where we practiced 4x a week.
This should have been communicated by the club directors of Hugoton, they knew the rules or have been entrusted that they should.
