mark h.,

your right about two things. it is too cold here in pgh. to play baseball now, but i still freakin' love it here.

i "don't forget what the human body has to do to get the sweet spot on the ball for an inside pitch". i plan on discussing this in partII.

and what you said about jack's observations will be included in my conclusion (if i ever get to it).
