The three of us were headed back from farmington and we traveled southbound on hwy 371 then headed west bound on indian service road 5. as we got on top of the hill, we noticed a bright light to the west and it was about the height of the mountain sitting in the sky. we traveled west for about 20 mins and the light was still in the same spot. all of a sudden the light disappeared. we looked at each other wondering what it was. about 30 seconds later we seen the light appear in the mountains but the light was smaller. it was there for about 1 min and it disappeared. we were all in shock and knew it was a ufo because relatives of mine had similar experiences.
