it's easier to have sex in a limo? I'm sure that's what they mean, as opposed to just looking in a regular joint.
Oh, I see ... but don't the anti-zoning zealots insist that "adult entertainment" has nothing to do with prostitution?
I'm sure these authorities just have dirty minds, and there's really nothing going on in those limos but folk dancing. (And how could they tell, if they've got tinted windows?)
I think it's about revenue. It makes it harder for the local tax authority to take their cut.
