I traveled straight through that area on November 5th, and I saw dozens of "contrails" that looked very similar to that one, which I believe to have been primarily NAVY jets.
Of course, these "contrails" did not evaporate like the ones I remember watching as a child, and by the time we neared L.A. the sky had been criss-crossed and transformed from cloudless to completely obscured.
Some people, like G. Edward Griffin and Alex Jones might refer to them as "chemtrails."
What In The World Are They Spraying?
