This was at the union cemetary in port washington. i am the 'cemetary sitter' for the port washington ghost walk and investigations. basically, i just hold down the fort and keep information going within the tour guides. this was a very clear night. no rain, no wind. no one was outside either, as it was cold in the high 30s. i sat down in my chair and see what looked like a spot light going across the sky, but it is not from the ground, or beaming onto the ground. it's just across the sky. and it makes almost like an old sprinkler system like movement. lasts maybe a minutes at the most. jerking a little bit, then moving to one side, jerking again, then disappearing. not even two seconds after this happened a skinny arrow-like shaped object moved in a bee line directly over my head. it appeared from over the top of one tree and disappeared over another. it made no sound. the night was entirely silent. it was shaped like an arrow. no lights. long body of it was dark, unsure of actual color, but along the body and the arrow parts were red, more like brick red, looking balls. not lights, though. i saw it for only a second or two as it flew over my head.
