| as i understand it, the one of the family living in the house near the circuit had a job working at the circuit, and the complaints about noise stated after he left/was pushed - sour grapes methinks. There's a huge comparism with music venues, where one individual or a few spoil the pleasure of thousands. The circuit was there well before the residents, so they absolutely without doubt would have known the level of noise before they moved in.
There's a metal scrapyard (hidden behind trees) a few hundred yards away from where i live, but it was established in 1903, and to honest, i barely notice it these days. |
