The obvious headline is "Leaving Las Vegas"

Often when there's a news story about something or other becoming more or less frequent or popular, you will search the story in vain for anything like, y'know, numbers to back up the assertion in the headline. But to its credit, the Las Vegas Sun reporter goes out and tracks down some actual data about the mass exodus from this city. I remember that when I moved here in 2006, I heard numbers like 3000 or 4000 people a month moving here, really incredible (but apparently then true) growth statistics. No longer.
