a slight history on Centralia is in the link I posted here. It's sad that you couldn't get any pics you'd dee worthy for the site.
On another note, the orbs in the creepy tree, they're basically supposed to be ghosts... Did you lose power to your digital cameras at any point around that church?
Also, if you ever take a trip up to Canada, check out Newfoundland, it's where I'm from, and there are plenty of ghost stories around this area, from suicide, to a man getting lost in a small wooded area for 10 days and coming out traumatized and mentally destroyed. He was perfectly sane when he went in to them. If you want to hear more Newfoundland stories, or for me to go deeper in to telling you the one mentioned, feel free to contact me some way.
