As we get older some of us put our roughneck ways behind us and try to live a more peaceful life, while others seem to get more violent and aggressive in their later years.
One particularly feisty gang of old dudes in Los Angeles are fighting to keep their beach local, giving Southern California surf culture a bad name.
People who try to surf Lunada Bay in Palos Verdes Estates are encountering a gang of rich guys calling themselves the "Bay Boys" who pick fights with anyone they don't want surfing their beach.
It may sound like the plot of a cheesy 80s movie, but this harassment has been going on since at least 1996, with assault charges filed against a few of the "Bay Boys" over the years.
And last May this localism lunacy was caught on video by Rory Carroll and Noah Smith of The Guardian, who came out to find their car egged with "kooks" written in surf wax on the windows.
