We were driving in the desert eastward on hwy 8 about 25 miles east of Phoenix, AZ at approx. 1am. I looked out the passenger side window on my right and saw two rows of 6 very large and bright lights, each the exact distance from the other. The row on the left was higher up than the one on the right. They appeared to be several football fields long and very close to us. The lights were a pale yellow and cast no light, but only glowed. My brother, who was beside me in the front passenger seat, was lightly dozing. I screamed for him to wake up and look out the window. We were both amazed at the sight and kept saying, "Oh, my God, what the hell are they." The lights on the top row on the left side suddenly went out, one after the other, in rapid succession, starting with the light closest to us. The lower row on the right followed immediately after in the same manner. The entire viewing lasted less than 3 minutes. The first thing my brother said was, "You know we can't ever tell anyone about this because they'll never believe it." We are both middle aged Grandparents and neither drink or do drugs. We also aren't prone to exaggeration, and my brother has always been a pure skeptic, though I have never doubted their existence.I have read about about, and seen many, many, pictures of UFO's but, have never seen pictures of anything quite like these two. Three or four months later in broad day light we were driving north somewhere between Los angles, and Monterey, CA and watched one doing bizarre movements above the mountain tops ahead of us on the west side of the highway. It flew straight up and would disappear, and then suddenly reappear several miles to the left just above a different set of mountain tops. Then it would fly from right to left, and left to right horizontally. It did a number of these seemingly impossible movements for about 20 minutes before it disappeared for good. We kept wondering if any of the other travelers were seeing what we did. It was almost as if they were saying to us, "See, we are real and you didn't imagine what you saw the other time."((NUFORC Note: Date is approximate. PD))
