A tri-meet will have two teams competing against each other in one gym, while the the third team could be outside of the gymnasium.
A school with two gymnasiums could do the same thing with four teams, never having more than two teams in a single gym at a time. If you bring five teams to one location with two gyms, have a bye round for each team, and all five teams can wrestle four duals and there never be more than two teams competing or in the same gym at any given point in time.
Saturday's with four duals and easily home before dinner would be pretty dang awesome if you ask me.
We have the time for change to happen. I'm hoping we get a couple more changes.
