I was driving to work november 3rd in las vegas. i saw this object in the sky not moving on my 22 minutes drive. once to the casino at red rock resort i parked on the top level 6th floor of the garage to observe the object better still thinking it had to be a balloon yet it was not teathered to anything around the ground.I took these three photos and still cannot seem to know what it could be hovering stationary above the skyline.
