Heavy spraying yesterday, 4/13 in SF Bay Area

I witnessed heavy chemtrail spraying yesterday, probably btw 10-20 planes over the entire day..not sure because I was inside most of the time. The sky was criscrossed with trails, then there was a thick haze, and at one point I looked up and saw a rainbow around the sun and an upside-down half rainbow in the middle of the sky. Really scary. Any one else in the area notice?

Kicking myself for not having a camera...

Trapper, you posted a link to a site about CT's in san fran back in 05, i tried it but it wouldn't connect. Did they move, or were they shut down? Any info appreciated...
