I find one of the comments in the PrometheusRadio.org's
FAQ just a bit intriguing:

"Many Ham-Radio people are crypto-militia wingnuts, but 
most at least have a strong libertarian streak ... and 
if they can go around spending your money on getting 
good deals for towers and whatnot, they will put them 
up for a case of beer."

If find this a rather strange comment.  What would be
the basis for this claim?  Any Hams on-list care to 
comment (low-temperaturedly)?
