I don't know if it is as much of "Let's get out of here as soon as possible" as it is for some brackets having 3 or 4 hours in between matches. Or even waiting 3-4 hours before they ever wrestle. It has been 1:00 before my son has wrestled at some tournaments, and that is what makes a long day. At districts he wrestled 7, 17, 27. He loved it.
I realize if you have an older kid wrestling also that you would be there all day too, but what about all the ones who don't have the older kid.....
