I never put any stickers on my car. There are just too many kooks with issues now and the simplest things tip them over.
I have a troop support ribbon, and another for a local who died in Iraq. Ironically a couple weeks ago I saw someone in a parking lot stopped looking at it. I think he was reading the name and date, but who knows. Gone by the time I got there. But you’re right, too many kooks.
