A hunting "city" is where you have like 10 guys go up on a ridge and set up a cook wagon or shack, living quarters, generators, electric lights , bar....the whole shee-bang for a week or so I have seen these and actually stumbling into one that helped me get my truck fixed when I broke down like 50 miles in....they had a bon- fire that was 10 feet across and like flames 8 or 9 feet high
