I am down here in Southern Illinois, literally right across the Mississippi River from St. Louis. There are no strip clubs of any note in Missouri, so competition between te two states is not a factor. The strip clubs in the East St. Louis area sit in two counties, Madison and St. Clair. The State's Attorney (government prosecutor) of St. Clair County (which includes East St. Louis, Sauget, Washington Park, and Centreville) has announced publicly that he will not enforce the law. The States's Attorney of Madison County (Venice--Roxy's and Pink Slip) about this topic, has said that in the first three months of this year, no LE agency has brought any citations/charges to his office.
In the clubs that I go to, there is no noticeable difference from pre-smoking ban. For about the first three weeks of January, management took about half of the ashtrays off of the tables on the main floor, but they are all back, and life is back to normal. I think that the dancers were going outside to smoke for about the first three days of January, then they cut out that shit.
