I heard a lot of young Hmong teenagers talked about a haunted bridge here in NC. They said that when you are the only car driving pass that bridge late a night, than you'll be more than likely to encounter something you don't want to witness.
Some Hmong boys was talking about the location one day and one of them decided he was tough and was going to proof to his friend that ghost don't exist. He took three of his good friend with him one night to the place and parked his car right in the middle of the bridge, opened all his windows, turn off his car, took out his key and throw them on top of the car. "See, there's no ghost guys" he tease his buddies. "Look, I'll even call for it", he put both his hand around his mouth and yelled out the car "Hey ghost!, we're here to see you, show yourself to us if you're real". It didn't take long, he yelled than same sentence three more times and all of a sudden fogs started growing around the bridge and it got so thick they can hardly see more than ten feet. Than right in front the car was two people, a girl and a boy all mud up and bloody everywhere just standing there. The tough guy reach out for his key on top of his car but can't find it, he tried to close the windows but his car was electronic locks. Than one his friend, the one on the passenger side claim up out of the window and grab his key from the top of the car and handed to him in a hurry. He was so scare, his hand was shaking so bad he couldn't put ii the key right. Finally got the car started and the windows close but he couldn't see anything outside except for the ghosts so he didn't know what to do. His friend on the passenger side than roll down his window and started apologizing to the ghost for disturbing them and that they've learned their lesson and will not bother the ghosts again. Than the ghost vanished, and the fog disappear and they made their way home.
After that story, a lot of young Hmong tried the ritual. Some failed but many witness the legend it hold at that area, I was going to try it one time with my friends but than chicken out or should I said smart out.
