The birthplace of Jerry Lee Lewis came to national attention in 2012, when a large police operation resulted in 30 drug-related arrests. It wouldn’t be such a big deal if it weren’t for Ferriday’s resident’s reaction, which was baffling. They were angry because the police were messing with the only stable industry in the town, production and distribution of crystal meth.
