That's a beauty.

It's fascinating to observe how terrain affects air flow.

I know of one particular site here, where there are flags
at three different heights; those flags can be flying
simultaneously in three different directions.

I've been mostly using this weather site, as it gives the
moon phases and star chart (my commute to work is at night):
http://weatherunderground.com/global...ons/71892.html
But it only gives the most general wind directions. Not that
it matters, because I'd use the same route to work regardless
of the wind, or any other conditions. It's the only route
available to me.

Riding to work on a clear, warm, full-moon summer night
is delightful (except for a certain bridge.)

cheers,
Tom
