Small auto sized UFO heading west at tree top height here in Sheridan Wyoming. It flew at a very slow slow creep along speed. I seen this UFO as I sat at Taco Bell window. UFO was heading west about three blocks from me I figure. UFO had two very small upswept V angled wings .I figure about 3 feet in length each. I watched it until I was served then I left area of sighting. Wish I had my binoculars with me.
