Ghosts in Las Vegas?

So a friend of mine and I decided that we were really bored. So we found a ghost tour of Las Vegas which sounded interesting enough. When we got there we were sat in a cheezy theater with a skull hanging from the procenium, a painted backdrop of brick and weeds, a fake tree, and small burts of fog clearly from a fogger. We were already two beers into the night so this was enough to get us giggling. The lights went out and the "scaryness" began. However when the lights came up an old man comes out and just starts talking about ghosts. He did some neat phycic tricks as he guessed the name of someone in the audiences relative who had died. Then some guy came out and lied down on a bed on nails with four large audience members stood on a piece of wood that lied across his stomach. It was impressive but I am not sure what that had to do with ghosts. Another old gentelman came out and read three peoples minds. He missed one so only got two out of three but still I am not sure how he did it. After the show in the theater we were brought out to a bus where we spent the rest of the time riding around the strip and hearing stories of ghost sightings in Vegas. We stoppped and got off the bus only twice, once at the Flamingo (my place of work-so not so pleasent for me), and the second was in a park where two boys were slain and are told haunt to this day. Someone, on the tour a year ago, caught them in a picture and that was passed around. I didn't catch anything on my camera. I took eerie pictures like the one above, but no ghosts, no orbs, nothing. On the tour we also drove many peoples houses like Redd Foxx's old place, Tupac's house (he was shot only two blocks from where I work-didn't know that!), Wayne Newton's house, and Liberachi's old place. Though the tour wasn't by any means scary or frightening I now know a lot about the town I live in (or at least I now know who died in what hotel and the best place to catch a glimpse of something supernaturaul). Wasn't worth the money that we spent but we got a free beer at the hotel when we got back so that made it at least tasty!
