Jerry:
My design approach for my tower system is to make sure I don't have to
babysit the thing, keeping it pointed in the "right" direction, when the
wind is howling outside. If you select your materials properly, and
install them with forethought to minimizing stresses, you'll sleep better on
those windy nights. In other words, do your cypherin' (I like that term.
Thanks, Jethro.)
