Dozens of chemtrails seen flying in crisscross patterns over Tracy CA. They left behind a large crosshatch pattern of jet streams.
Throughout the entire day, from 8am to 7:30pm, I witnessed at least a dozen planes leaving long chemtrails over Livermore, heading south east over the Del Valle reservoir, all flying the same path line.
I saw another 2 planes create an X in the sky over Livermore. All of the planes seen today leaving long trails behind them were white and appeared to be unmarked. I've never seen a multicolor planes leave long contrails behind them, only the white ones.
This is the most chemtrail activity I've witnessed in the Bay Area on a single day since I began paying attention in spring 2012.
