It is not. I just telephoned the District II North Sub-district tournament director and we will hold the weigh-in at 08:30 A.M.. I have yet to verify with the South and am attempting to do so, I have left a voice mail for the tournament director.
When they get to HS they will have to maintain and weigh in after competing all day anyway, maybe it's good experience. But on the otherhand the squeaky wheel gets all the grease.
Kansas High School doesn't follow the rules there either. They should be weighing in right before the duals, not the morning of. Again, kids are softer because of Adults.
