Several years ago I read - Beneath the Neon by Matthew O'Brien. I just can't seem to put it down re-reading and re-reading. Since reading I been taking pictures of the tunnels/drain whenever I see them, mapping them,researching them and even having conversations with some of the homeless on the bridges between casinos who call them their homes much to the wife's dismay. . I have even gone back and forth with Matt via email and facebook. I have become nearly consumed with them as I have a fascination with things like this ............ abandoned buildings and homes, tunnels, caves etc. So this last trip - pre Memorial day I made up my mind I was going to visit one and go through it. Disclaimer - these tunnels can be very dangerous - do not do this without knowing exactly what you are getting into. My beginner tunnel/drain was near the Las Vegas Welcome Sign ......................... got up very early and went. I encountered one homeless man at the entrance to the tunnel. He did not want his picture taken - said his name was Charles. Nice guy - I felt at ease around him. Asked him how long he had been living in the tunnel. 2 years - had a business got sued, IRS seized all his assets and boom his life went to shit. He had much disdain for the IRS and the government. Here are some pics ............ The tunnel to the west littered with beer cans was basically a bathroom for those living down there - I did not go in. The smell was over powering and I was told loaded with black widows the farther you go. The tunnel to east had about 5 or six cardboard boxes where Charles and those down there would make their camps. No one else was down there at the time other than Charles. It comes out at beside a wedding chapel across from Mandalay Bay inside a 30 foot barbed wire fence just outside the runway at McCarren. I also visited and went in a much larger tunnel that is under the LinQ hotel ............ this one was amazing. I'll post some pictures of it later today ......... got to get some work done.
