Pretty cool article. Says the boat sat in international waters and they'd ferry gamblers out. This one that sunk was near San Diego so I wonder if it was their under their LCN family's control or LA? Was this a thing anywhere else with a sea port like Nola, Tampa, or any of the East Coast families?
