I've been to G'Burg 30 times or so, including several at night. I never saw or felt anything. But my wife completely wigged out one time in broad daylight near the Peach Orchard. She just made a running break for the car in the middle of a trivial conversation. She said later that she was overcome with an overwhelming sense of imminent death.
WOW, that's wild. My dog wouldn't get out of the car!
