The UK Sun (an admittedly sensationalist source) claims that hundreds of people are living in the storm sewers beneath Las Vegas, scraping by on coins left in slot machines. The underground community is documented in a recent book called Beneath the Neon.
It is estimated the population of the underground community could be as many as 700. As well as credit-hustling, they earn their money off the wildly excessive city above by begging and "dumpster diving" – raiding bins and skips.There are around 350 miles of flood channels running under Las Vegas. Most inhabitants are in the area under the city's strip.
Another couple, Amy and JR, have lived in the tunnels for two years, having moved to Las Vegas in search of work, wealth and a slice of the famous Sin City action.
Putting down the Twilight vampire book she is reading for the third time, Amy, 33, explains: "My husband and I have been down here two years this week.
"We were living with my mom in California but the house was full and we had to leave.
"I heard Las Vegas was a good place for jobs. It's the city that never sleeps, with all the bright lights, and I'd always wanted to come.
"But it was tough and we started living under the staircase outside the MGM casino. Then we met a guy who lived in the tunnels. We've been down here ever since.
