Nation to celebrate the 4th with caution

NEW YORK - The Fourth of July fireworks display billed as the nation's
biggest is trying to up this year's oohs and aahs with a pyrotechnic
novelty: exploding shells aimed at the water, not the sky. The
so-called nautical shells are supposed to explode on the surface of the
East River, remaining illuminated for a few seconds before fading out,
said Robin Hall, executive producer of the Macy's Fourth of July display.
