I agree, T-Bone. I believe I was "in" later than you (78-97), every time I can wrap my head around another piece of this, it is a blessing to me. I'd like to think that I'd gotten all the old twi cobwebs out, when you shine your finely tuned light on it, lo and behold, another one pops up! Thanks, because when I see it, I can begin to eliminate it.
