After a week of real horror due to the "horrific and violent acts of nature" witnessed this week. NPR's "The Writer's Almanac" http://writersalmanac.publicradio.org/index.php?date=2011%2F04%2F29 gave a perfect poem: Mother by Ted Kooser. Hit the link above to see or hear it.
These lines are awesome:
a storm that walked on legs of lightning,
dragging its shaggy belly over the fields.
