I was camping in a remote area of Western Wyoming with my brother and his wife. We were sitting around the campfire when, at 10:45 PM, we heard a jet flying high over head. When we looked up we saw an enormous triangle shaped craft. It was nearly equilateral and had three white lights forming a triangle at the front, one white light at each back corner, and a larger pulsing red light in the center. It was flying moderately slow, East to West and based on other observations we made later, we guess it was probably about 20,000 feet high. Judging sound and other jets we saw flying the next day, it would take about four airlines to equal the width of the back end of the triangle and probably five to go from back to front. It was shocking to see the size of this. I'm a normal everyday person, graduated college and working in a career. This is the most bizarre thing I've ever seen and I'm left just searching for answers.
