I didn't list Florida because I doubt that Florida will remain snake-friendly if it ever was. As Florida has more problems with alien reptiles breeding in the Everglades, the legislature will likely pass laws making reptile ownership more difficult. Of course, like most laws of that kind, these laws will be a huge nuisance to people responsible enough to try to follow them and will do almost nothing to make the irresponsible people act responsibly.
Nevada doesn't have any state laws against prostitution, but each county in Nevada sets its own laws. If I remember correctly, prostitution is illegal in Las Vegas. I suspect that this prohibition has nothing to do with concerns about public health, morality, or organized crime possibly controlling the trade (which is actually less likely if something is legal). Instead, I suspect that the city leaders just don't want people in their rooms giving money to a prostitute when they could be losing that money much faster in the casinos. The legal prostitution is most likely in smaller towns that don't have the money or infrastructure to have big gambling establishments. Prostitution is a business that doesn't require much infrastructure. Yes, that's a cynical view of things, but I tend to be cynical sometimes.
Strangely enough, I've heard that the laws against prostitution are less restrictive in other states than one might imagine. I read somewhere that there's a state in the New England area where prostitution is legal as long as everything is done indoors. If the any part of the transaction occurs outside, then the police can arrest either party. If not, the laws don't cover it.
In any case, I'm less worried about blue laws than I am about reptile laws. I know that Louisiana recently passed a law requiring licenses to own certain kinds of snakes.
