I couldn’t let this day pass without commenting that we have yet another day of absolutely blue sky in Pittsburgh.  It looks just like that blue square at left (which is actually a picture of the sky).

Without a single cloud, it’s pretty hard to see migrating hawks.  I’m sure they’re up there but there’s no way to see them in a sky this blue.

OK, so I’m asking for clouds.

I’ll live to regret this request next month in gray November.
