Schwarzenegger's reason for attending 49ers practice appears to be the simple fact that he was in the neighborhood.
The governor was in Santa Clara to deliver a speech at the Bay Area Council Outlook Conference, an elite powwow of executives and elected officials being held next door to the Niners' practice facility in Santa Clara. One of the topics covered was "An Insidious Threat for Nations, Companies and You: The Growing Cyber War."
Schwarzenegger is uniquely qualified to discuss cyber war, as he is a robot sent from the future by evil machines.
The governor did not comment on whether he would be visiting any more 49ers practices.
But several 49ers surely declared that he would "be back," doing their best Austrian bodybuilder impersonations.
