Yes Peter I know the story of ghost sightings. :-)
All I can say to that is.......
I lived most of my life next to this park, as a young woman I often took a shortcut through the park alone and very late at night, I never saw anything of the sort and never ever felt uneasy there.
It's a beautiful place though lacking some of it's former glory...these days there is more to fear there from the living than the dead. :-)
Do you know the Spideyj ... Lee Johnson, is head park ranger there?
