QSL. It only confused me a little. Bottom line? 100 MPH is a helluva
dangerous wind velocity of anything. Under-building your tower system would be
a gross error.

You KNOW that? Jeez, you don't know what the failure mode is going to be.

I quoted the whole text relating to the building inspector.
Sarcasm? No kidding.

I'm not an engineer or wind force expert - I'm a professional tower guy.
I only quote the established procedures and specs - I didn't formulate them.
But it doesn't matter what the conditions are. The spec is the spec and
that's what you build to with NO SHORTCUTS.
