<rant> Go to Ripon, follow the tracks, 1800 feet, 90 knots, 1/2 mile in trail, and... SHUT. THE HELL. UP!!! It was really busy today, and it got to the point where the controllers were behind the eight ball, giving instructions to aircraft that were already past Fisk... Oh, and another PSA: The NOTAM specifically says DO NOT PROCEED BEYOND FISK without ATC instructions! Turn left, go around Rush Lake, back to Ripon, and start over. Anyway, controllers were super-busy, and people keep keying up and saying "But we're a flight of three!" or "Can I have runway 36 instead?" NO, you may not. Unless they specifically ask which runway you want, shut up, take what they give you, and do not speak on the radio. At all. They need every bit of frequency time they can get - Their mic was pretty much open. Stepping on ATC helps nobody! Because of that, they were having to repeat instructions and couldn't talk fast enough to give the arriving aircraft instructions in time. Result? A controller had to jump on and press the reset button. "All aircraft past Ripon, turn left heading 270 immediately, proceed back to Ripon and start over." </rant> Please, read and follow the NOTAM. There is no reason to ever key a mic going into or out of Airventure VFR unless ATC specifically asks you a question. These controllers are the best of the best, let them do their job.
