Yes indeed, and it was horrendous. It would take pages to tell you about it, as it went on for four years. They were neighbours whose fields adjoin our and my parents houses. They started with a couple of trail bikes and quickly went to having 13 or 14 similar vehicles on their fields, sometimes for 8-9 hours a day. The noise was unimaginable, and made me so ill that I lost over 4 stones. You couldn't hear the television over the noise. Our illustrious council's Environmental dept got involved (police couldn't do ANYTHING as its private land). We had to record the noise and write logs. The paperwork would get lost, the recording machine would be unavailable etc etc the list goes on and on. I would stay in work sometimes until about 10 at night to save going home to the noise. I couldn't think straight at all. I also couldn't bear what it was doing to my elderly parents. After this had gone on for what seemed like forever, just as it was about to go to court, the woman dealing with it went off with stress. I could have told her about stress!!! We spoke to another council official, the one who probably should have been involved sooner, and he intimated that she was being threatened. It only stopped because the couple concerned split up and he moved away. He was a really thug. You couldn't talk or reason with him. He told the council it was his effing land and he'd do what he effing wanted on it. I'm actually ring as I'm writing this, even though its 10 years ago. It probably sounds a bit pathetic now, but believe me, to live it was truly horrendous.
