This. Exactly this. Thanks Bunta.
It is not a drag day, it is a happy laps sesh. If you want to go to the drags, go to Willowbank. You can give it a squirt down the straights but this is only meant to be cruising speeds.
The reason that they don't like people lining it up on the straights is because if someone comes around a corner and goes into a car that's slowed down. There will be a complete shit fight which nobody wants.
