I was always embarrassed by the "remain seated during the national anthem" JW dictate.
My parents were folks who never like to draw attention to themselves, so they taught me this clever workaround for sporting events: A few minutes before the anthem is to be played, take a walk to the bathroom. If they still haven't finished by the time you are done, just hang out in the walkway below the seats until they have finished, then walk back to your seat.
Of the dozens of MLB games I have attended over the years, I don't think I ever saw the first pitch of the game from my seat.
