Via Mark Evanier comes this excellent link about Matt Frondorf, an engineer who drove from New York City to San Francisco with a camera facing out the passenger-side window. He connected the odometer to the shutter release so that the camera would take a picture every mile. He started at the Statue of Liberty and wound up at the Golden Gate Bridge. Read his story and see a slide show of the pictures along with a map showing where he was when it was taken. It's way cool.
