Farm supporters should DRIVE IN MORNING AND AFTERNOON RUSH HOUR TRAFFIC in downtown Los Angeles.
Obey all traffic laws. Make sure your vehicle is properly licensed [current tags], no violations [no broken tail lights, etc.]. Bumper stickers and signs that don't obstruct driver's view are legal.

Just drive in critical areas such as the passage from the southbound [in the a.m.] 5, 101, Pasadena Fwy into downtown intersection. Reverse to outbound lanes for p.m. rush hour]

With enough cars you can cause GRIDLOCK. This forces "apoliticals" to confront issue of shameful eviction, because they're stuck in a traffic jam.
