The first event was well run and well reffed. I would say though that the schedule needs to be strictly adhered to. Call the teams to the field twice, then DQ them. In at least one instance a team was called 5 times.
I GUARANTEE that if a team gets a DQ they'll LISTEN for their name next time. That will cut down 90% of the problems right there.
I would also say that after many of the games there was a lot of milling around on the field as one team or another discussed the game with the refs. There's no reason to debate calls...the game's over and the outcome isn't going to be changed. Get the captains to sign and move 'em off.
The last 4 games of the finals were played in dusk/dark and so the outcome was no doubt effected. It hurts when you miss second place by 17 points and you've shot out some your own guys because you couldn't see who they are in the dark...
I suspect GLP #2 will fix everything.
Oh, and make sure you have enough Hamburgers!
