FILE - In this Oct. 4, 1997 file photo, a herd of cattle is led into the parking lot of the Cow Palace during the cattle drive to the 53rd Grand National Rodeo in San Francisco. There was a time when the Cow Palace, a cavernous exposition hall built near San Francisco's old beef slaughterhouses, was a revolving door for the country's most famous personalities. Within a span of months in 1964, the Cow Palace staged Wilt Chamberlain, the Beatles and Barry Goldwater at signature moments in their careers. But the picture is much different 46 years later. The arena aged and fell into a state of financial disarray and physical disuse. As budget woes paralyzed California lawmakers every summer, the landmark has faced threats that it would be shuttered and sold. (AP Photo/Eric Risberg, file)
