Gerard..questionable to me since, why would 1970 have special significance to him? Did I miss something? Why not 1963, or 2007, or...?
Ghost crowd-control must have been a problem.
I've speculated that Amy's presence at Collinwood revived Quentin's ghost in 1968, so why not Hallie's arrival in 1970?
Not that this idea would actually fit in with the world of Collinwood spiritualism or anything but...I sometimes catch those (Most Haunted, Dead Famous) ghost hunting shows and I heard one of the physchics involved talking about this kind of thing just the other day. He was referring (I think) to a recent investigation of the Queen Mary.
PS: Recommended tours, Newport RI, Savannah GA, Harpers Ferry WV,Woodlawn Plantation (near Mt. Vernon Va, seasonal) London, Edinburgh ...Looking forward to a new one on our vacation this year
