I have also made numeroous trips. Every now and then there would be certain sounds that seemed out of place, as well as orbs of different sizes, motions, and clarity. Some can be chalked up to dust, but some are different. I am not a huge believer in orbs, but sometimes you cant explain them away. Also, one trip last Sept. we took a trip out there and did some EMF and DVR. When has some direct answers on the EMF and when synced to the DVR, there are whispers being heard. I had my doubts until that trip. There may def. be something there. However, I don't think it has anything to do with the urban legend.
