I had just gotten to the motel last night about 9.30. When I went to the car to unload, I saw some flashes out of the corner of my eye. When I looked up, I saw a huge rectangular shaped craft. At first I didn't know what to think. It flashed two short flashes and 1 long flash at me, then it was gone.It reminded me a huge fluorescent light. It had 3 or 4 rows of blue 'bulbs'.This was after I saw the 4 lights for 4 or 5 hours, earlier on the drive in the Nevada desert.
