I agree with Ashton; a lot of effort goes into keeping the schedule going but we have no control over weather or accidents, just two of the many things that can affect schedules.
Have you ever spent an hour or two in the tower? If not then I doubt you can appreciate what goes on behind the scenes to run an event.
As to noise, the local requirements are beyond our control. Noise bylaws apply to most tracks, some have just not been enforced. It is short sighted to abuse the noise regulations as we could easily end up with nowhere to race.
