Were you referring to the base vehicle registration stickers that are normally placed in the lower left hand corner of the windshield? If so, ok, I see what you’re saying. But many installations have stopped requiring those in the past few years.
I think folks may have took it as a generalization towards vets and some don’t like that, right, wrong or indifferent.
I was just saying I don’t “advertise”, I see many that do. Some that more than make up for many of us who don’t.
It’s simply a matter of preference.
