Actually I saw an article that said Las Vegas had 15 actual made guys there.
Chicago has a soldier in Las Vegas. They always had a soldier there running things for them Since Marshall Caifano.
Mob activity in recent years, or lack thereof, tells us all we need to know. The 2003 raid of the Outfit-connected Crazy Horse Too strip club was the last big mob-related event over the past decade. In 2008, Gambino associate Salvatore Reale was ordered by a judge to return $4 million in a business deal but that's not exactly big news. The mob's sports betting networks still extend out to Vegas, and I imagine there is interest in some legit stuff like clubs, restaurants, etc, but that's pretty much it. You've got individual mafiosi living there or passing through but apparently not any permanent, active crews.
