Before the storm

I'm spending some late-summer quality time in my backyard hammock on this hot afternoon. There's a storm threatening, and I can hear rumbles of thunder to the west (around Holtwood, according to the weather map). The breeze is picking up, the crows are circling around and cawing and for some reason the wind chimes are playing a jaunty version of the "Final Jeopardy" tune. And what is that worried-looking white rabbit doing checking his pocket watch?
