UFO Sighting in Richmond, Kentucky on July 13th 2012 – I walk on a late night walk and it appeared out of nowhere and hovered above me for a couple of minutes

I was walking at night in Richmond, KY, and out of nowhere an oval shaped object slowly just hovered above me, maybe 150 feet above me (at most) and 50 feet from me. I had no idea what it was, or what I should do, or who I would have told. It had many lights on it, they weren't that bright, like they didn't want to be seen. I wanted to take a picture of it after watching it for a minute or two and as soon as I pulled my camera out it flew off, faster and quieter than I have ever seen or heard any air craft before.
