Here's some more background about wind noise:

My neighbour's sound system is not that loud; I merely choose to use my own Ass Kickin' Sound System responsibly. I could drown him out whenever I choose to....I choose to sleep through it instead.
Anyway- tomorrow is when I'll find out the noise a 5' turbine makes and slap you down. In the meantime i have drinking to do.
