I’ll start with the easy one. Way back in the 1990′s, 1991 specifically, giant U.S. flags started popping up at American car dealerships all over the country.
They were designed to remind you to Buy American. (Although even at the time, many “American vehicles” were made in Canada, or from overseas.)
It didn’t really work so hot, so most of those flags, in front of your Oldsmobile,* Plymouth,* and Saturn* dealerships for example, went away.
And these days? Well, I don’t know, really.

Maybe this giant flag means that an American car dealership used to be here.
I think it was a Ford store with lots and lots of Added Dealer Markup…
*A kind of car, back in the old days.
