Folks; I am sorry, but I hurt my back and I just could not mess with trying to lift my scope and do a public viewing session. I am on the couch with a heating pad, watching baseball playoffs. No, I am no eating bon-bons;-) I hope that if some of my students showed up, that they saw enough to write up a paragraph or even two and get a grade. Clear Skies and Advil to us all; Steve Coe
