It's generator city when we go to our big motocross meetings in England but the rule at every meet is off by 10pm. We are not there for a leisurely weekend and find this cut off acceptable. BUT there are always a few ignorant people who flaunt this while running the noisiest Aldi bangers outside their caravans/motorhomes. Some even have long cables so it is not disturbing them personally. We just go out and tip them upside down after 10pm. Always works.
