Any idea if the grape vines and orange groves in Los Angeles are in a

Even in cuckoo California, the prevailing winds are from the west to the
east. Anyone looked at the Mojave Desert (garden spot of the universe)
lately?

Seriously -- if you need a painless introduction to the subject, I
suggest the song "Acid Rain" by the Austin Lounge Lizards.

...Acid rain, keep on fallin
While her name I am callin
I walk the shores of Lake Champlain
in the placid acid rain.

Walked together through the forest full of dying trees
Tasted the sulfuric acid on the April breeze
Went canoeing on the lake, the fish were floating by
She read me her manifesto; I had no reply..."

I wonder what causes it.

It's obviously not air pollution. Any ideas?
