Several old concrete rearing pens on the canal near the beach where people raised their own chum for fun,, some even did it in garbage cans... When I was a cop I talked to several people who were doing or or had done it... The state went around and shut them all down by the late 90's mostly...

The state and tribes run the MAFIA racket on fish and wildlife and cannot let anyone get in on their money machine,, they regulate in the name of safety and science but its only about money and extortion...
