DOSWELL, Va. - Was it a UFO or something else that hovered in the sky over Kings Dominion Amusement Park this weekend? That's the question many are asking after watching a video posted on You Tube. The video shows a large dark hollow circle formation in the middle of the sky, near one of the park's rides. WAVY.com contacted Kings Dominion, which is located 20 miles North of Richmond. A spokesperson said it is a smoke ring from the park's Volcano ride. Whatever it was, it has people talking. Let us know what you think by leaving your comments below...
