It's rather obvious when a guy in a suit (along with lots of random cops driving around) spends all day standing outside my apartment that the Obamanator is going to drive by either tomorrow or Monday on his trip to SF. I would have never noticed if it was a normal looking guy in casual clothes, but a guy wearing a suit standing in one place for 4 hr in the suburbs is rather unusual. The corded earpiece in the right ear also kind of gives it away. I figured by 2011 they'd have wireless earpieces that looked like hearing aids.
