We have a riders meeting at our races and no I wouldn't want it broadcast to the crowd. Sometimes people, including the promotor get called out and it isn't for everyone to hear.
They are borrrring anyhow as a whole.
Funniest thing is at our riders meeting one of the first things the promotor says is to ride careful the first heat. There is no practice in speedway, you go to the line and let er fly. Sure enough after the first round of heats theres always a few guys crashed out for the night. The last riders meeting I made it a point to say that all the riders in my sons class were in the main, have fun but don't do anything stupid till the main. Out of the six riders only two were able to make it out in the main, two destroyed bikes and two destroyed bodys,
Yep buy a pit pass or better yet race, then you can hear whats being said.
