My friends and I were driving home from Santa Cruz. I was in the backseat and looked west to see a very large object in the sky.

On our way home from Santa Cruz. We were driving north. I was in the backseat and looked west and began staring at what i thought was the moon at first because of its size and brightness. after about 10 seconds i began to realize the moon wouldnt be in that location at that time of night. the craft was glowing a bright yellow color. it was about 2:00am. about the time i realized what i was looking at the craft moved inside of a cloud which began to glow the same yellow color. I told my friends in the front seat to look. i became very emotional and began to cry out of amazement from what i was looking at. this object was massive unlike anything ive seen in the sky before. it was about 200 yards in length. my frienda began to freak out when they saw the glowing clouds. we were still driving north and about 20 seconds later the craft and cloud had dissappeared behind a hill. we turned around to try and find it again but it had vanished. we drove west instead of north attempting to chase it but no other lights were seen.
