You all might think me corny/crazy (or moreso than you already do
) but in my car I have a laminated 8.5x11 piece of paper with "Thank you for your service!" printed on it. Whenever I'm in traffic and get up to someone with a veteran plate I pull it out and try to get their attention. Ok, maybe the driver isn't actually the veteran, but I bet the story gets back to the veteran...and that's just as good.
