Guys, one thing that I have seen in a lot of posting on boards is that there can be a LOT of regional differences. What is the standard for one area of the country may be the worst answer for another. What works in the cold, damp northeast where they have high energy costs may be the wrong answer in the dry, hot southwest. And I think that this applies to about any HI subject you can consider.
Harold has been around a long time and is well respected. I'm sure that he comes from his experience in his location. Relax a bit, eh? And don't forget that we get people from all over the world that look at this board. And he doesn't need me to explain for him but I've seen it too many times where something like this is the case.
