Central PA guy here.
OVERWHELMING # of Trump flags, stickers, and yard signs, probably into the hundreds.
I think I’ve seen 2 Biden yard signs, and one flag between Myerstown and Hershey, down to Reading, PA area.
I’ve only see a couple Biden signs and bumper stickers myself. Rarely even see anything while driving the I-405 corridor from Lynnwood to Bellevue out here in Washington.
