Yes, it's that time of the college football season when those bronzed, militaristic brutes from the University of Spoiled Children come play our sweet, gentle Cal Bears. As part of their presumptuous triumphal march through the city, the hundreds-strong USC Marching Band took over Union Square this evening for a pep rally. Rumor has it that later in the evening they'll be headed to (where else) the Marina. And it looks like you can still scalp some tickets for the game.
