As a thrill seeker i would will say that a graveyard is a place to start.But as a paranormal research group, graveyards poses alot of problems.First of all a group is trying to find scientific evidence to prove or disprove the existence of ghosts. When reviewing that evidence, alot of times that evidence can be easily contaminated from animals, and the weather.Secondly, most of those people residing(lol) in that cemetary prob passed of natural causes, so the chance of them lingering is not that great.
