You will not hear many good things being said about New Jersey Gov. Chris Christie these days. Between getting caught closing down bridges, holding up disaster relief funds, and his generally abrasive nature, he doesn’t make for a very sympathetic figure. But I’m a forgiving sort (no, not really, but it sounds good), so when he does something right, I’m willing to throw the man a bone. So here we go: This week, Christie signed legislation known as Dusty’s Law, which gives extra legal protections to guide dogs.
