It can be heard in the howling wind. Or the aroma in a store where pounds of sugary delights are purchased and given to neighborhood youngsters on the one night of the year when it’s really OK to roam the streets, asking for candy. Halloween is just around the corner. And so are alleged ghosts, spirits and haunted houses. Are they only the subjects of horror and comedy-filled books, movies and TV shows? Or, after centuries of wondering, do they provide any legitimate clues to possible life after death? It doesn’t matter if you believe in ghosts or not – they are, literally, everywhere, and their otherworldly presence seems more at home as All Hallows’ Eve inches its way to October 31st. On this week’s “Edge of Reality Radio,” historian and connoisseur of the bizarre, Marc Hartzman, will be our tour guide on a journey through America’s supernatural history. We’ll look at famous haunted places and people – in other words, all things strange and spooky.
