I was in the pool around 3:00 by myself and I looked out towards the lake and noticed 3 semi shiny triangles going horizontally around and around. I believe they were the size of a refrigerator, but smooth canister shape in a triangle going around with NO sound, just rotating. I believe the objects had red and white strips with a square of blue, much like our flag. It was a clear day, 85 degrees with no planes or contrails. I jumped out of the deep end, I’m 68yrs old, grabbed my I phone, looked up and started recording video. I took one photo, put back on video and when I did point up again they start to leave one after the other. I told my 45 yr old son to take a look cause I zoomed in and out while filming. I didn’t see them. He immediately looked at my videos slowing them down and he saw three fuzzy images in a triangle. He made me a clip and they were fuzzy, I saw them very clearly and there was no smoke, clouds, or contrails. This was my encounter with something I knew immediately was very real. There is no wonderingly question. I knew what I saw.
