Dull silver, kind of an aluminum color pyramid shape. It would flash periodically, and I couldn’t tell if it was reflecting sunlight or self-illuminated. Did not look like an airframe I’m familiar with, and I’m a bit of a airplane buff. Did not see rotor blades, did not see any jet exhaust. It was small but with a solid blue and clear sky it was difficult to figure out approximate size. I’d say maybe the size of a Cessna. It was moving in a bit of a swaying motion like a boat on water. My fiancé was driving and we were a little lost at the moment so tension was a bit high, I, very unfortunately didn’t get my phone out to take a video, although it might not have come out with much detail, it would’ve been worth a shot, I was waiting to get our bearings, and I lost it in the tree line.
