We do campfires as many nights as possible. We even do it at home in the backyard. To us, it's an atmosphere, a feeling, to sit by the fire and chat. I would have to consider it just "RVing" and not "camping" without the campfire....My wife left my extra shirt hanging by the door unwashed after and evening by the fire at our last camp out just 'cause she said the smoky smell on it is nice reminder of good times.
I did notice for the first time a month or so back in a KOA that they had a campfire rule I had never seen before - it said that the fires had to be out by 10PM. I laughed at that. I can see "no unattended fires" but "out by 10pm" is ridiculous.
The community campfire sounds interesting. I have never been to a CG that did one yet.
