SIMON: And seven in ten Americans are planning to get their screams this year through decorations, costumes or creeping into a haunted house. NPR's Allison Keyes visited some haunts and reports on the industry's multi-billion dollar battle for your souls.
ALLISON KEYES, BYLINE: It's dark. The people in front of you are cringing. And, hey, what's that stuff hanging from the ceiling?
SCOTT SIMON, host: Libya faces many challenges as it grapples with life after dictatorship. Of course, Moammar Gadhafi is dead. His fugitive son, Saif al Islam, is reportedly in talks with the International Criminal Court to face charges of alleged crimes against humanity. The city of Bani Walid was the last place in Libya known to have him. It's also the seat of the largest tribe in Libya. NPR's Lourdes Garcia-Navarro travelled to Bani Walid yesterday and found a tribe that's aggrieved and city that is seething.

John McCarthy, the American mathematician known universally as the father of Artificial Intelligence, died last Monday at his home in Palo Alto. He was 84.
WEEKEND EDITION's Math Guy, Keith Devlin, knew McCarthy and has this remembrance.
KEITH DEVLIN, BYLINE: I first got to know John McCarthy when I arrived at Stanford as a visiting professor in 1987. He was 60 years old at that time, with a towering and, to me, somewhat daunting, reputation.
This is WEEKEND EDITION from NPR News. I'm Scott Simon. This week, the Congressional Budget Office released a report showing that the gap between wealthy and poor Americans has become much wider than it once was. We'll have a story on how changes in the tax code may have contributed to this situation, and we'll look at the Occupy Wall Street movement. But first, we turn to NPR's Andrea Seabrook and Robert Smith for a seasonably appropriate analysis of how the income gap has changed over the last 30 years.
SCOTT SIMON, host: This week, New York's Taxi and Limousine Commission reminded cabbies that honking is against the law except when warning of imminent danger. They could be fined $350 for using their horns, just to snagged affair, vent steam over traffic or jolt pedestrians are looking up at the skyscrapers and lingerie billboards to move more quickly. Mike Castillo has been driving for 30 years.
MIKE CASTILLO: Human stupidity in New York traffic is huge.
SIMON: And says cabbies ho when they spot dangerous less street smart drivers miss.
The Port of Entry at Nogales, Ariz., is in the midst of a massive upgrade to ease congestion caused by up to 1,500 Mexican trucks crossing each day. Nearly two-thirds of the produce consumed in the U.S. and Canada during the winter come through here.
These Mexican trucks stop at warehouses near the border to transfer their loads to U.S. trucks. That's the way it's long been done. Gary Hufbauer, a senior fellow at the Peterson Institute for International Economics, says that adds cost.
