Falkenhan, 32, was planning to buy his own ticket after his shift ended.
"I'd buy a new truck and a new boat," he said. "Then I'd go on my own fishing tour."
Roxie Breece, an assistant manager at a Cenex convenience store in Ogallala, Neb., said clerks have sold far more Powerball tickets than usual over the past week.
"Tomorrow's going to be a nightmare for us," she said. "With everybody out shopping and the drawing on Saturday, we'll be really busy."
Lingle, who is also the executive director of the South Dakota Lottery, says this weekend will be "telling."
"To my knowledge we've never had a large jackpot run like this fall over a major holiday," he said.
Frank Scorvino, of Toms River, N.J., is in charge of buying lottery tickets -- including Powerball -- for a group of about a dozen fellow construction workers. If they win, he said, most of them would purchase new houses and cars, and some might go on a cruise.
South Bend, Ind., resident Dameon Smith says he'd retire from his job at the Hummer plant in Mishawaka, Ind. He said he'd share with family, friends and people he doesn't know.
Chad Robinson, 41, a chef at a Cleveland restaurant, had an option during his break Friday: Put down $2 on Powerball game or go next door to Ohio's first casino. He bet on the lottery, saying that much cash would change his life "drastically."
"I figure I'll make a lot of people happy with it, not just myself, spread the love and live my life out -- parents, loved ones, kids, co-workers, charities," he said.
Terry Fowler, 50, of Conneaut, Ohio, was visiting family in Tennessee for the holiday and stopped in a gas station in Brentwood on Friday morning to buy Powerball tickets. He's a regular player.
"I want to see more than one person hit it so they can share the wealth," said Fowler, a sales representative with a food service company. "I don't think any one person needs $325 million. If 7 to 10 people hit that, they will live like kings."
