Please comment?!?! Friday the 13th Witches Bridge?

Yesterday me and my boyfriend went out to Witches Bridge in Nebraska. It is supposedly haunted. We went when it was still light out. He said last year when he went he had some spooky things happen along with his friends that I know.... I was thinking about going out there this Friday night and see if anything happens.... Also it would be the Friday the 13th So I thought it would help a little I guess. I don't believe in ghosts and that kind of stuff but I find it cool to hear about. I want to be proved wrong when we go up there. Do you think this would be a cool night out? I wanted to do something just weird I guess... Do you think the ledge is true about some witch haunting that bridge? How can I believe that something could be out there?
