RE: [TowerTalk] static cat

David- Thanks much; it's about as I suspected;and the bottom line was an 
opportunity for some Lawyers to enhance their retirement funds. It sounds 
like they were trying to punish the reviewers for merely reading something 
and saying "yes".
I have my own  opinion about the effectiveness of a "Bleed-off" system, 
based on 16 years at one location that is prone to strikes. (The evidence 
is abundant in the woods around me). This is enhanced by having worked in 
an explosives plant protected by standard Army Ordnance procedures for 38 
years. I think a "bleed" system helps a lot, but don't think that "fuzzy" 
receptors help the bleeders. Of course, my experience amounts to merely 
limited anecdotal  bias, not statistically defendable data.
Thanks-Bill-W4BSG
