How do you know you're in Kansas City, Missouri? Follow the smoke, and listen for this:

"Hi, may I help you?"

At the famed Gates Bar-B-Q in Kansas City, "May I help you?" is a kind of mantra.

It's how people standing in front of the barbecue pits greet all who walk in the door, while ribs, brisket, turkey, and for all I know, pillow stuffing sizzle, pop, and get saturated with smoke and the signature sauce of Ollie Gates, the barbecue master.

On a recent wintry day, Kansas City eighth-grader Yak Nak sat before a Missouri state Senate committee. He was there to tell lawmakers why his family had sacrificed to send him to a parochial school.

"Even though it was a struggle for my family, the reputation of the public schools in my area was not as good as my parents would have hoped," he said. "They knew there was no time to waste when dealing with young minds, and education was more valuable than any money they could save."

Consider this: Yak Nak and his family are refugees from Sudan.

Stepping out of my hotel on Friday evening, I could see cars backed up for miles, stretching all the way around the Benghazi's biggest lake, not far from the shores of the Mediterranean.

Horns blared in every direction, but not just car horns: bull horns, oo-gahhorns, vuvuzelas, aerosol-powered horns, even a bagpipe or two. The air smelled of exhaust, gasoline and the occasional whiff of hash. It was a cacophonous mess, overwhelming, painful to the ears, joyful, extraordinary.

Every year, roughly 750,000 high school dropouts try to improve their educational and employment prospects by taking the General Educational Development test, or GED, long considered to be the equivalent of a high school diploma.

The latest research, however, shows that people with GEDs are, in fact, no better off than dropouts when it comes to their chances of getting a good job.

This is raising lots of questions, especially in school districts with high dropout rates and rising GED enrollments.

A Second Chance, But Is It Enough?

American officials have long complained about countries that systematically hack into U.S. computer networks to steal valuable data, but until recently they did not name names.

In the last few months, that has changed. China is now officially one of the cyber bad guys and probably the worst.

Hourly workers at General Motors will soon be getting profit-sharing checks of up to $7,000 each after the automaker reported record earnings this week. President Obama may also get a political dividend, two and a half years after a government-engineered turnaround.

Obama reminded a group of United Auto Worker members this week that, back in 2009, his rescue of GM and Chrysler had plenty of critics.

Bighorn Sheep Canyon in Colorado holds a chuckling ribbon of water, with a highway running alongside. Artist Christo wants to drape sections of it — almost 6 miles' worth — with long, billowing panels of silvery fabric.

"The silver-color fabric panel will absorb the color," he says. "In the morning, it will become rosy, in the middle of the day, platinum, and [during] the sunset, the fabric will become golden."

There were two sides to the story of President Obama’s appearance at a San Francisco fundraiser Thursday night. One happened inside the Masonic Center on Nob Hill. The other took place immediately outside.
