Did you read the Time Magazine article on Las Vegas a couple issues ago. Talking about the "wife swapping" Friday nights at the House of Blues. I guess that is what all those LV commercials are selling to everyone. No Rules, etc.
For a while Vegas sold its kid-friendly theme with amusement rides and ads geared to setting family vacations there. Now they are going back to their sin-city roots, and what you mentioned fits right in with that picture. Sex clubs there are proliferating. Clearly someone is patronizing them (in multitude). Maybe we should be checking those strip clubs for jihadis at this point in time, as that's what the last bunch did before their evil deed was commenced.
