Nebraska State March 9th
Oklahoma State February 15-16
Texas State March 1st
Colorado State ??? Looks like 6U-14U are on Feb. 10th and Fr.-Soph. are on March 8th.

I'm not saying this is the answer, just something to think about.
Have 16U seperate after High School State. At this age the kids do not really care about the venue, just a chance to wrestle for a state title. It could be held anywhere. This makes room for 6U to be added. State gets moved to the first weekend in March. We are able to watch NCAA's, Big 5, High School State, and the little guys can go watch the Froshman and Sophmores in March if they want.
