I heard a rumor that Anderson Cooper was in town today, shooting a live show this evening. Can you substantiate this rumor? Please?

While we here at SFist haven't heard jack about a Cooper visit, we're happy to guess! Maybe he's here declare his much speculated upon orientation at tonight's opening of the San Francisco LGBT Film Festival?

OK, maybe we should stop guessing before we get a call from CNN, and turn it over to y'all smarty-pants readers. Anyone else seen him? Anyone know why he's in town?

Update: Friend of SFist Brad tells us: "I was watching his show last night, he's 'keeping them honest on the West Coast"'this week. Tonight SF, tomorrow night Seattle" So, we know what he's doing for work, anyone else see him out and about?
