These pics were taken at last weekends practice session.. I can say the noise was no where near what I expected, and really isn't much worse than outdoor.. The fumes are being handled by 2 large exhuast fans, which do an excellent job.. The rule at the track is no starting Nitro in Pit area, and there is a mandatory 1 minute of silence between races, which helps clear out any hanging fumes, and gives marshalls time to put things up and get to their marshalling areas..
