Well, it IS improper to fly a flag from the back of a vehicle. Anything that could make it dirty or torn is taboo. I wish firefighters would stop doing that. Full-size flag on the back of a truck - flails out to hit other things, and drags on the truck, and gets exhaust. Well-intentioned, but not full respect.Far more respect than ceding to a ban of displaying Old Glory....I have an old ball cap with the flag on it and it states, "These Colors Don't Run"....
