Just read an interesting article about noise pollution. A few neighbors are suing an owner of a race track. They have documented and called the police weekly since 1997. They have also had to pollution control agency bring out a device to leave and measure levels. It shows only a few times where it would cause pain! They say its so loud that they can't hear each other 5' away outside during a race.
Just thought it was interesting to see it has taken 9 years of complaining against a obvious offender to get this to go to court. Makes me wonder how long it would take in my county to get a court date set against a loud neighbor.
