my two cents back...

>New Mexico fire of a year or two back comes to mind...
I'm talking about grass fires here. These run out of fuel very rapidly
which makes their control fairly simple if you know what you're
doing. Burning overloaded woodlands is a whole different matter. How they
are going to sort out the western forest lands that have become overgrown
is far beyond my expertise. It may be that much of it needs to be logged
pretty soundly to thin it out, low grade it if you will, to get the junk
out. This overgrowth is of course the result of bad logging and more
significantly fire suppression for 100 years.

10,000 years of native American management with fire? Works for me.

The chaperal areas are tricky devils too. Very flammable vegetation, steep
slopes with gravity winds and gol dang houses right in the middle of
it. One word friends: GOATS!
