The kids and I were at Lang Ranch Community Park this afternoon when I looked up and saw these pretty spectacular contrails in the sky. It was a beautiful, sunny day but the air was fairly cool. I've read contrails last longer when there's higher moisture in the air, which at 66% humidity today was definitely the case (and apparently we finally have a cold and windy winter storm coming on Monday).
This contrail cross was seen in the direction of Cal Lutheran University. Perhaps someone was trying to make a statement. Others thought perhaps this was an X, marking the Conejo Valley as "the spot" that we all enjoy living at.
