Sea lions back in SF

USA Today reports on the return of sea lions to San Francisco bay.

After an abrupt disappearance that left tourists disappointed and experts baffled, sea lions are slowly returning to San Francisco's Pier 39.

Last fall, after ballooning to a population of 1,700 animals layered two and three deep on the docks, the sea lions departed as if following orders, leaving behind only a few stragglers.

Marine experts believe the animals might have traveled 500 miles north, looking for fish and colder waters along the Oregon coast.
