Tonight, if we're lucky, we'll look skyward and see specks of light streaking across the night sky. It's the Perseid Meteor shower, late summer's elusive fireworks. I say elusive because clouds or city lights often edge them out of eyesight. But some years the heavens have cooperated. One summer we saw the meteors from lawn chairs by a lake in Arkansas; another year we camped out in our neighbor's driveway. More often than not we just turn off our porch light, walk outside and wait. The brilliance is fleeting and it's easy to think you've imagined it. But you haven't. It's a glimpse of the beyond, and it's unforgettable.
