Until you read the fine print, this billboard in midtown looks like something Phill Kline hoisted in hopes of discouraging your purchase of the latest Jugs magazine. But put away that new neck massager long enough to read the small type in the right-hand corner, and you'll see that it's a public-service announcement. "Make an emergency plan at ready.gov," it reads. The site is run by the Department of Homeland Security, which wants to get your family ready for tornados, hurricanes or George W. Bush declaring himself dictator. It's not a good idea, by the way, to simply tell your fam that they can find you at the porn store in midtown.
