http://www.cbsnews.com/8301-201_162-57555976/powerball-jackpot-soars-to-record-$550-million/ CHICAGO As Americans went on a ticket-buying spree, the Powerball jackpot rose to $550 million Wednesday, enticing many people who rarely, if ever, play the lottery to purchase a shot at the second-largest payout in U.S. history. Among them was Lamar Fallie, a jobless Chicago man who said his six tickets conjured a pleasant daydream: If he wins, he plans to take care of his church, make big donations to schools and then "retire from being unemployed." Tickets were selling at a rate of 130,000 a minute nationwide -- about six times the volume from a week ago. That meant the jackpot could climb even higher before the Wednesday night drawing, said Chuck Strutt, executive director of the Multi-State Lottery Association. The jackpot has already rolled over 16 consecutive times without a winner, but Powerball officials say they now believe there is a 75 percent chance the winning combination will be drawn this time. If one ticket hits the right numbers, chances are good that multiple ones will, according to some experts. That happened in the Mega Millions drawing in March, when three ticket buyers shared a $656 million jackpot. That remains the largest lottery payout of all time. Yvette Gavin, who sold the tickets to Fallie, is only an occasional lottery player herself, but the huge jackpot means she'll definitely play this time. As for the promises she often gets from ticket purchasers, Gavin isn't holding her breath. "A lot of customers say if they win they will take care of me, but I will have to wait and see," she said. In the hours before Wednesday's drawing, Associated Press photographers fanned out across the nation to meet ticket buyers and ask about their lottery fantasies. Here's a look at what they found: ... Paralegal Pat Powell was buying her first Powerball ticket at another store in Atlanta, even though she acknowledged her odds were probably "zero to zero." ... Horticulturist Kevin Brags buys tickets at the store two to three times a month. He says he usually picks numbers higher than 32 because so many people use numbers 31 and lower, largely because of birthdays. The birthday theory didn't scare off Paul Kruzel, a retired doctor who chooses the days his children were born. ... © 2012 CBS Interactive Inc. All Rights Reserved.
