One of my favorite of all places to visit (particularly at night!) is England's Silbury Hill, which - as I have come to learn over the years - has become a veritable magnet for paranormal activity.
In 1997 (when the above photo was taken), I learned of two sightings of large "black panthers" having been seen at the foot of the hill at some time back in the late-1960s.
Two years later, I received details of a ghostly, ancient horseman seen behind the hill in 1974.
And in 2010 I was emailed concerning an encounter with what sounds very much like a Mothman-style creature - way back in the 1950s.
One of the days, I'm going to have to write all this up...
