I don't agree. I think it's a choice that each area has made between law enforcement and local governance. Regarding the St. Louis area, it really depends on which jurisdiction you are in. St. Louis County has over 90 municipalities. The neighboring counties are also fragmented but to a lesser degree. There are areas (mostly more rural) where it is legal and loud, some where it's not legal but enforcement is lacking, and there are quiet areas in which I assume enforcement does happen.
