It has been a tempestuous summer. Tempestuous in terms of meteorology rather than the emotional, personal sort. Most days seem to begin or end with lightning strikes and bursts of rain. I've spent several evenings enjoying the sky's displays on my front porch--watching looming clouds turn to heliotrope lanterns backlit with streaks of fleeting light. It's almost as pretty as a firework show, although a good deal less predictable. On warm evenings when the bugs are at bay, it's a pleasant way to clear your mind from a cluttered day.
