If the tournament is schedule and ran as an official tournament USA wrestling will insure you for an unsanctioned event. Ark City has did everything that I can tell where you are still covered. I believe that Spex had a post earlier asking about insurance and Richard had posted info on the insurance if you want to look back on what it covers.

Remember that with all insurances, that there is still a deductable and when an accident occurs you need to put down your USA info as well as your regular ins. at that time. Don't wait to do anything.
