It's Saturday, Aug. 19, World Honey Bee Day. Happy birthday to TV producer/screenwriter Gene Roddenberry (1921-1991), creator of 'Star Trek.' Today in 1964, The Beatles began their first U.S. tour in San Francisco's Cow Palace. Expect a cloudy morning, with gradual clearing and a high in the upper 70s. Help honey bees live long and prosper today:
