Good points Ron. As I am fond of saying "I am American by birthright and Southern by the grace of God!" Neither of which I had any control over, so I feel no guilt for my personal "Human Condition". I care about others, always help those who ask, and I accept the benefits I receive in life as undeserved gifts from my Creator; and I challenge the population of this world to do the same! Happy Thanksgiving. Mark at Aero

OK, broker my new rule since I'm just sitting around waiting for orders from the Commander of Thanksgiving anyways. NFPA 13-2010 ed. 8.6.5.2.1.8 exempts piping less than 3" from the 3x rule, otherwise.... And that rule has always (always is at least 1999 edition if not older) been there. (Big change editions to 13 I recall 1954, 1991, 1999, and everything this century). Happy National Eating Day. Do take a moment to reflect about those hat are going hungry in this country where we throw more food away per capita than most of the world produces, and how you feel about that. Are you an "every man for himself" type or a "we're all in this boat together" person? Or somewhere in between? We show a collective appearance to the world that is a composite of "me plus us" to one degree or another. Like going to a date are you satisfied with the way we look, or not, or don't care? Sorry to talk politics (but not partisan mind you) but I'm feeling thankful and ashamed at the same time.
