You must have a different demographic than where I live. Doesn’t matter what kind of gathering it is, if there’s trouble there’s always a firearm involved. And yes, someone got shot at the ‘brawl’ that made the news.
We are in western Jersey on the Delaware river. We can see the Delaware from our house and Pa. is on the other side. On certain nights we can hear them for hours on the rural roads.I have never heard of a problem with guns. But it could be like you say we are an entirely different demographic.
