If I ride in Rolling Thunder on Memorial Day in Washington, DC I salute the Marine on Memorial Bridge with my right hand. Always have but I don't ride in this event every year. Now I understand they have made it legal for Vets to salute for special circumstances. Never knew it wasn't legal. I guess it's nice of them to make this legal but if they hadn't I don't think I would have stopped doing it.
Never memorize something you can look up.
