From my mother, who works in North Philadelphia, in the glorious swing state of Pennsylvania:
On several street corners are enormous “Ask me where you can vote” signs, manned by people who seem to know. Enormous red arrows then direct people to the proper polling place, with signs along the way. At one polling place relatively deep into the neighborhood, there was a longish rainbow line of locals and students together; most of the other places did not have discernable lines, but there are a lot of people out on the street. I also passed a community center sending out two enormous trucks playing vote-for-Obama rap music.
From my father: Half the registered voters have already voted!
