I live in the Salt Lake area as well, Monday of this week was just like the previous post, square pattern of 10 to 12 planes in front of the sun. North and south of the valley normal contrails. I also mentioned this 2 weeks ago, some dick named Noble jumped all over me, I could give 2 shits what Mr. tough guy behind the keyboard thinks. I live here and I know something is not normal, what it is I don't know but I haven't seen anything like it in my 45 years of living here.
