Houdini's Halloween Storm?

On Halloween night 1936, Bess Houdini, the widow of famed escape artist Harry Houdini, attempted to hold a seance to contact her dead husband.  Harry, a well-known skeptic, claimed that if a supernatural crossover was possible, he would be the one to attempt it. So, Bess gathered their closest friends and fellow magicians and converged onto the rooftop of the hotel in attempt to contact the other side. Legend has it that after about an hour of the ritual, a violent thunderstorm broke out -- but only over the hotel and nowhere else in L.A. The group quickly scattered and they never attempted an official seance ever again.
