Thanks, Rick.  Again, some good points, and I'm ready to set aside the "pen"
with respect to va-birds if you are.

You ask:

No, I can't argue that--mostly because I know very little about Virginia's
regulatory scheme.  And certainly, caution is warranted to some degree.

I'm troubled, though, by the nature of your comments.  I don't have anything
against regulation of wind, but I'd like to see it undertaken in a spirit 
of true
fairness.  Such a spirit would acknowledge some things that I haven't seen
in your posts:

- Our current system of generating electricity is an ongoing environmental
disaster.  Coal, the source of more than half our electricity, exacts huge
environmental costs at every step of its lifecycle, from the habitat
disruption and pollution that accompany mining to the air pollution,
greenhouse gases, and mercury from combustion to the habitat disruption
and pollution that accompany waste disposal.

- Global warming, caused in part by the fossil fuel combustion from which
we obtain ~70% of our electricity use, threatens habitat destruction on a
global scale and massive impacts on wildlife.

- Wind energy, notwithstanding its flaws, remains one of the cleanest and
least-damaging options we have for generating electricity.  The task before
us is not to prevent or slow it as much as we can, but to capture its benefits
while minimizing its direct impacts as far as reasonably possible.

You've defined the issues with wind pretty well.  I hope that you are equally
willing to recognize its benefits.
