I can understand the appeal of going ghost hunting. You are running around in the dark, listening for spooky noises and scaring yourself. It sounds like fun. Kind of like telling scary stories around a camp fire, only instead of a warm fire, you're in an old house, or a creepy theater, or on a bridge of an active train line. Well, that last one doesn't sound fun, but some people would disagree with me. Some of those same people are now dead.
I really can't comment on this story. It's just too stupid and too tragic.
