folks who doesn't let a little thing like physics get in the way
of what you think is right.

I'm listening, explain why a round or square wooden fence post is
stronger if the width of the post is not a factor.

I, and one or two others, postulated that the round post would be
stronger because it maintains the integrity of the tree (assuming the
post started as a whole tree). No engineers have responded to rebut
any of those comments.
