Sign in Arkansas

By the side of the road, south of Little Rock.

Keith Elder lives in Hattiesburg, Miss., and works as a software engineer for an online mortgage broker. Last week, he was driving home from Little Rock, Ark., when he spotted a sign by the side of the road.

"Pre Depression Price Sale," it read. Keith hit the brakes and went back to take a picture, then blogged about it and posted it to Flickr. Since then, more than 130,000 people have seen the image. Yesterday, he told us why he just had to turn around.
