I thought the problem of finding a source for CN had been resolved 
when  YARA International, the importer of CN, changed the formulation of 
their product so that it would no longer be an oxidizer, thereby taking 
it off the HASMAT and Homeland Security high risk lists. While it does 
seem to be the case that the formulation has been changed, apparently 
that is not enough to satisfy our 
ever-vigilent-guardians-of-our-freedoms over at Homeland Security, and 
they are keeping it on their very-bad-stuff list. I learned this today 
from Brad Lawes (Lawes Agricultural Services), and he has again decided 
that the hassles involved (security camaras, elaborte paper trails and 
precise tracking, to name a few, are too much to make it worth his while 
to continue carrying it. Can't blame him.
      So the situation is back to where it was a few days ago when some 
other sources were mentioned in various emails responding to my initial 
panic. If anyone has any current information from suppliers or other 
suggestions, it seems that there are quite a few of us out here who 
would be interested in hearing about it. Seems appropriate to put any 
such info out onto the whole list serve rather than just individual back 
and for... that's my own opinion.   I'll listen in from Montana for a 
week.... Jake
