I remember once when someone tried to shame me for using a generator at night for AC in a Walmart lot. We had actually gotten reservation at a state park for a simple overnight, but found the site far too unlevel to use. We ended up on a hot June night in southern Missouri at a Walmart. Temps was 90+ when we pulled in around 6 pm, and there were already a couple of semis with their diesels running. We fired up the gennie and relaxed. “You were rude.” “You were too noisy.” Those were the things I was told when relating the story later. Yeah, like my gennie was going to bother anyone with those semis running all night! Is there a time and place when running a generator is rude? Maybe around tenters, but not in a parking lot filled with semis in a hot summer night.
