I could compare and sympathise with those living by Redlands.
For many, many, years, we had an illegal motorbike problem, the little dears would be down, up around, from 10am until well after dark in the summer.
Often with no exhausts, or peppered with holes, just to make it even louder, it absolutely spoiled every nice day, we had to sit indoors with windows and doors shut. There was no control on it whatsoever, even walking the dog was a nightmare but that's not to doing with sound. It was the sound that was all over. There was no hope of a definite 'going home time'
This can affect one mentally.
Now Swindon speedway was a different matter - hardly anyone complained about that - granted it was a bit further away, but you knew when it would start and when it would stop.
I was happy to hear the speedway, it meant summer was here.
Not one person ever said to me that it didn't bother them or that they liked the sound of the illegals!! Most selfish bunch of people ever.
It took an anti social behaviour law, and community Support officers to get us anywhere on that one. And, of course, when the Police discovered they were mostly stolen bikes and they were using them as getaway vehicles.
