[TowerTalk] Tree's and Screws

This is obviously an old article. Cadmium plating was popular and it  
is very good from a corrosion standpoint. The plating process uses a  
cyanide rinse which can create environmental problems. For a while  
cadmium plating was banned in the US but now it is expensive so it  
will not be easy finding Cadmium plated hardware for your trees.
