Welcome to fabulous Las Vegas! But if you see this iconic sign as you're driving, you're not in Las Vegas. In fact, most of the famous landmarks and the big casinos aren't in Las Vegas at all.
They're in Paradise, which isn't even a town. It's an unincorporated area in Clark County. A quarter of a million people live there, but it has no municipal government.
