Tunnels Beneath Las Vegas: radio program

npr.org

I heard this today while listening to NPR where I live. It's a good listen. About the hundreds of people who live in the hidden matrix of tunnels beneath the Las Vegas Strip. In one part a man makes his living at casinos around town, doing what's known as "silver mining," which means he looks for credits left behind on slot machines. I thought the line at the end is moving, "glancing around at all the tourists, no one's checking out the gutters. They're all looking up, at the flicker and pulse of the lights."
