As part of the No Kings Day protests, Third Act Ohio had two banners on a pedestrian overpass at I90 and E 72nd street just outside of Cleveland, Ohio. 

They clocked 60 cars passing per minute on each side of the road. They were in place for 2 hours meaning they were seen by over 10K vehicles. The number of people honking and waving in support vastly outnumbered those giving the 1-finger wave.
