As far as I know, at least here in Southern Oregon we don't have live sex acts on stage. In fact it's almost impossible to open a strip club here.
There was a 1/2 hour show the other evening about a new law passed in Oregon that lets "anything go" in a night club. I don't remember the specifics but I'm sure I can Google them up...
From the Oregonian, Oct 9.
"But that's just where we are after the high-court's recent contribution to jurisprudence and decadence -- if there's a difference in the case of Oregon v. Ciancanelli. With an opinion that features more twisting, contorting and heavy-breathing than patrons find at a strip club, the majority has now made Oregon the only state where live public sex shows are protected "free expression."
The Oregonian, BTW, filed a friend of the court brief in favor of Ciancanelli.
Try this website, I think it explains the case that made live sex acts legal in Oregon - maybe a club will be opening up in your neighborhood soon, selling RockStar, of course...
