WE HUMANS SEE SIGNS everywhere: signs of spring, signs of aging, signs the economy is about to implode. Then there are real signs, and the Washington, D.C., area is rife with those. Some are serious and some are funny, albeit sometimes unintentionally so. Here then are half a dozen signs we’ve noticed in town. There must be hundreds more, all around the city and the surrounding areas. Send us your favorites and we’ll put them together in a gallery—maybe one for each neighborhood? We’ll see.
