I-5 UFO Sighting appox 40 miles north of BakersfieldMy parents and I were driving north on Highway 5 and saw what seemed to be an extremely low flying aircraft. It was so low to the overpass we were approaching that it looked like it was going to land there. I could not make out any distinct shape of the craft. I thought it was a plane at first because of blinking white and red lights like those normally seen on a plane, but the way it was moving seemed inconsistent the capabilities of a normal airplane. It seemed to disappear for a moment then we saw it over the fields to our right. The fields were full of trees (what I assume were nut trees) of similar shape and size. Suddenly the field lit up and it seemed that the craft was down amongst the trees. It got dark again and we then saw the craft behind us. It circled around again to the overpass, and although most of the time the craft was dark, there were three lights that turned on for a few moments and then were extinguished. I continued to watch for the craft out the rear car window....saw the blinking lights for about 30 seconds then got out of range. In hindsight, we should have stopped the car for a better look, but we were on a long drive from Phoenix and anxious to get home. We did not hear any sound coming from the craft, however our car windows were rolled up.((NUFORC Note: Witness indicates that date of incident is approximate.
