Nice pic. Unfortunately I am a Vet and when they stayed in the locker room during the National Anthem and shamed the Vet that came out, I stopped honoring them. They are now the Pitt. Kneelers. I am also from the Pittsburgh area and am ashamed of them.
Multiple solutions though. but it is mostly symmetrical and easy to figure out by guessing!
Hint / spoiler alert: it's the logo for the Steelers!
