["Jerome Osentowski" <jerome@crmpi.org>]

I have had good results with solarizing the tuff grasses, and most 
presistant weeds like Canada thistle.  We demo this method in the natural
weed control video.  see add on our site.  the town of Basalt uses
indurtrial  vinegar with some suscess, but I find the fumes toxic to be
around, and I have had better luck with solarizing and following with a
thick
layering of sheet mulch.   This even works with quack grass.  I also have a
frezer full of rabbit raised on weeds.   jeroe
