HUDSON, Ohio — Some stood alongside heavily trafficked highways, big enough to read a quarter-mile away.

Others occupied quiet corners on dusty county roads.

But an overwhelming majority had one thing in common: They heralded the name TRUMP.

Over the course of eight days, while traveling some 3,000 miles by motorcycle across the northern United States, I was steadily confronted by presidential yard signs.

I idly recorded those in support of Donald J. Trump until, after the first few days, the number approached 100. I eventually lost count.
