Clad in gangster garb, Vegas Mob Tour's guides weave salacious tales culled from Dennis Griffin’s The Battle for Las Vegas: The Law vs. the Mob, which recounts interviews with a retired FBI agent, on a bus tour that was featured by the Chicago Tribune. At 6 p.m. at the Royal Resort, the tour kicks off with the ceremonial sacrifice of a fedora before fact-laden narratives relate a sordid history of Sin City's mobsters. Buses shuttle passengers between sites of murders, disappearances, celebrity fatalities, and other crimes carried out by notorious figures, such as Benjamin “Bugsy” Siegel, Frank "Lefty" Rosenthal, and Tony "The Ant" Spilotro. Wielding exclusive insight from felon-turned-witness Frank Cullotta, the tour peeks behind the shadowy curtain of intrigue that surrounds the crooks, killers, and puppy salesmen who overran Vegas in the 1970s.
