Blue Corn, I didn't see your post until Rick had closed the thread, so I didn't have the chance to say thank you. I was glad that I had the time to spend looking into these matters, and am satisfied that I finally understand the whole picture. I knew it would rile some people (but didn't expect rock stacking to get thrown into the mix!), and felt prepared for that, but I did not do as well as I had hoped in responding to the backlash without getting caught up in the fray.
I'll do better next time. Peace.
