You guys must live in Utopia, among ourselves, us car guys, our kids are usually well behaved, adults too. It's the spectators that pull up in the mini van with a carload of devil babies that bring out those signs. The guy who wants to assault you because you are asking him to remove his 9 year old from your car because he just stabbed your seat with his pocket knife or sharpied "SUK" on your dash. The grinning guy with the "i'm with stupid T shirt" the one with the arrow that actually points up, that hung around your car so he could snag your shifter knob, cause he is in need of counseling, or time served. The 350 pound guy who just has to do he secret test on your running boards that bends them and laughs to his 92 pound friend that it would still be attached if ya hada dun it rite. Those signs are not for the regular folk, they are for the hateful, stupid, rude and just plain ignorant people out there who need a sign to keep them from putting their hand in the snow blower, head in a log chipper or drinking anti freeze. While I do not advocate the signs I do respect in most cases the types of situations that cause them to be placed. Next time you see a gent sittin there with a sign, ask him why it is there, you may get a heck of a tale out of him. You guys need to go shopping with your wives, see society at it's finest.
