I have two. First It is a very windy day. We have set up a stage that has several of those corrugated plastic walls and at one point you have to pass through a hallway made of them. I am the guinea pig. At the beep I start and make it to the hallway halfway down the wind really picks up. THE WALLS FALL ON ME IN THE MIDDLE OF THE COURSE. Hmm stage problem so I get a re-shoot. We add weight to the stands for the walls and even a tie down or two. I get to be the guinnea pig again. I start and get to the hallway again and the wind really starts blowing but the wall stays up I get to the end of the hallway and the wind gets a good hold on the wall and blows down away from me so much for slicing the pie I am now fully exposed to the bad guys. That was the last straw for that course it was not even used for the match. If you want the second you have to share some of your fun at matches.
