Bob, you have broken out in Blog!
What a well done presentation. You succeeded
in the number one goal of the best teachers;
that is, to get the reader (or student) to thinking.
As different as we all are, I think each of us
finds a zone. Artists and writers find specialties,
for lack of a better term.
Your personal comments are interesting and
informative.

Haha...yes, Ed I've broken out and there appears to be no treatment for it. "Think, people! THINK!"
Bob
