Bumper Fish? I'm not a person who likes the idea of putting the Fish sign on the bumper of my car. Actually, I've had the "Ichthus" (Fish) symbol on my dashboard for years, in hope that the symbol will work to spur me on to better driving, with the result of a somewhat improved witness out on the streets. Bill at Provocative Church posted Five Reasons To Pry Off The Fish Symbol saying that the symbol itself is not necessarily a helpful witnessing tool when displayed on one's bumper. I'll stick with my dashboard!
