Obamajam extended to Glendale *

Crowds are already forming, and streets already closing, in the USC area for President Obama's campaign rally this afternoon. But some new plans to be aware of: the White House has announced that the Obama motorcade will shoot up to Glendale about 3:30 for an interview with Piolin at the Univision studios on Central Avenue near the 134 freeway. Presidential motorcades usually mean freeway closures, which in the middle of the Friday afternoon get-away crush can be crushing. Obama is scheduled to leave Glendale at 4:05 p.m. for LAX, the L.A. Times says. The route was not announced, of course. Even if the president moves by helicopter, there's still a ground motorcade of aides, media etc. Good luck out there.

At the USC end of things, Neon Tommy is planning extensive multi-media coverage.

* 12:30 p.m. traffic update: Obama flew to USC by helicopter from LAX and will fly to Bob Hope Airport in Burbank to lessen the traffic load later this afternoon. The 134 freeway (and presumably I-5 leading into the 134) will still be closed for at least a few minutes each way for the motorcade to Glendale and back.
