Finally, an intelligent conversation about Power Poles, if a bit off- 
topic! Funniest thing I've heard on the sig in a while!

AFAIK, there is no special marine treatment. Typical pressure  
(arsenic-copper) treated 4x4's last about 4 years in tidal areas, and  
rot at the area which is intermittantly exposed to air. A power pole  
would last  longer, but if it were under load it would not be long  
until the load bearing ability was compromised.
