I generally (not always, but generally) agree. However, I see so many incorrect 30.06 signs that I take a completely different approach to those. I take those to mean "I'm pro-gun and you know it because you know this sign isn't right. I'm also appeasing the idiots who don't know this sign means exactly nothing, legally."I read the 30.06/07 sign as saying "I'm an antigun liberal and I don't want your business", so screw them...
So every time I see a gunbusters sign or a 30.06 in 1/2" letters, I take that as an explicit, open-arms welcome to people carrying a concealed weapon.
