While I like the first two and will buy a few, they won't go on the back of my truck. I don't have stickers/things that ID me or make me a target. I have a Veteran license plate but that's about it (and well enough!). I will put them on tool boxes, wear at M&G or gun show, post on bulletin board at the local masonic lodge etc.
i always thought having one with a chicken on it with no firearms was a good idea, for those of us whom tend not to place any sticker on their car with firearms related images on it
