It was 7:15pm when i left the house and began driving west up the hill on del webb dr.To the summit clubhouse for an event. i immediately noticed the large craft in front of my car above the houses in front of me because it was flying too low and i thought it was going to crash into the neighborhood. i was going 30-35 miles per hour and the craft stayed the same distance from me so it was also going very slow. i thought when it didn't crash into any homes that it was perhaps in trouble trying to land at the las vegas airport. however, it continued to move at the same speed but just a tad higher all the way to the top of the hill where i was going. when i pulled into the parking lot i saw that the craft turned a little more to the north since it had been traveling west all the way up the hill. the craft had three red lights - one on the left side, one on the right side and one in the middle. this is why i originally thought it might be a large military aircraft but it was flying too low and there was not a sound coming from the craft. then as i attempted to make out the shape it reminded me of the very large "v" shaped object i had seen when the craft was over phoenix, arizona. the entire sighting took about 12 minutes and the night was very clear.
