well about 4 years ago. i went to see "emilys bridge" in stowe, vt. i dont know if you've ever heard of it. but they say its haunted by a girl named emily. it was in the 1900s. emily was waiting for her lover to meet her at the bridge so they could go and get married, because their parents did not want them to wed. he never showed. so she hung herself on the bridge. they say when people crossed the bridge with horses/or cars. that she would scratch them when they drove through. some say they can hear her.
anyway. i went there one halloween. there was couple there, and they were taking pictures with there digital camera. the girl said she was in the middle of the bridge, and she heard something.
i didnt so much have an experience myself. but just being there felt wierd. and the bridge is creepy.
