Somebody I know emailed me the picture of that recent thing posted here from out west, don't remember which state. This object floated above the river for maybe less than 30 seconds, rotating slightly then winking out. My wife freaked out because we were still about 40 minutes from takeout and had know where to go. we paddled over to the side and sat in the woods for about 20-30 minutes, but the mosquitos were eating us alive, so we got back in the water. I got one photo off before it dissapeared. About 10 seconds before it dissappeared another circle thing seemed to pop out of the center, which is when my wife started screaming at me to take a picture, and that's what you see. I really don't want to know what it was, because to this day it gives us the creeps, but since I saw the other one my wife thought it might be best to share the experience. I'm not going to mention the name of the river because our cabin is near there.
