During a summer outing in a Yosemite, Ca. forest campground, we arrived around 1:00 pm in the afternoon and my wife started the generator to get lunch cooking. There were two women in a tent camping about 40 feet away, and they both came over and told me to shut down the generator. When I told them no, they refused to leave. This went on for about 20 minutes, even when I threatened to call the ranger. It was in the national forest and I just refused to shut it down until my wife finished cooking. I told them it would take 20 minutes, but they wanted it shut down now. The finally left, but were fuming.
