The object hovered across the sky silently, gleeming against the sun as it disappeared into the horizon.I saw the object because I was laying down flat on the grass. It didn't make a sound. It was circular, but I couldn't tell from the angle if it was completely circular or a disc. My guess is that it was a disc. It was silver, almost like a stainless steel color. I followed it with my eyes till it reached the horizon, heading north. Then the sunlight reflected off of it, giving the object a bright gleem. After that it was too far for my eyes to see. My friend and I were conversating at the time. We both shut up as soon as we saw it and didn't say a word until the object was long gone. Interestingly enough, just two days before we saw the object, I saw, along with a group of other people, two A-10 Thunderbolts circling the area. I've never seen A-10's in that area. The field in which the sighting occured is next to a heavily wooded area, known as the Savannah Preserves. There isn't anything out there but, wild life. Still, the preserves aren't that large and the object had to have passed civil areas as well.
