According to the CHP Traffic Incident Information Page, a group of protesters gathered in Richardson Grove.  At a little after one, there were around 50 people.  Twelve were in the roadway blocking trucks from going by. At some point a banner was unfurled.

Kathy Epling said on Facebook that her neighbor in Piercy called her and reported “our frontage road is lined with CHP vehicles and officers (she estimated 15 cars, but that seems like a lot). The officers said they were there in case the protest in Richardson Grove got out of hand, but, said one “it won’t”.”

But the incident is now marked as close.
