Shoppers at Columbus Park Crossing brave Black Friday

Shoppers were out in full force at Columbus Park Crossing today for Black Friday — the day after Thanksgiving and one of the busiest shopping days of the year.

Circuit City swung open its doors at 5 a.m., and by 5:45 a.m. the parking lot was full of vehicles. Cars spilled into the lots of nearby Lay-Z-Boy Furniture Galleries and Cheddar's Casual Cafe, both of which were not open yet.

Inside, hundreds of shoppers waited in various lines throughout the store — some simply to find out if desired items were still in stock.

The scene was similar at Toys "R" Us, where, at around 6:30 a.m., a line of shoppers with toy-filled buggies snaked around the whole store. The toy store opened at 5 a.m.

Columbus resident Pat Sikking, 50, was shopping for her 24-year-old twins, one of whom is a mother of two young children.

"I don't know why I let my girls talk me into this," Sikking laughed. "This is my first time doing this, probably my last."

Sikking said shoppers shouldn't take things too seriously on Black Friday.

"You know when you come out here there are going be lines," Sikking said. "So you've got to laugh, you've got to have fun. That's what I'm doing."

Up to 132.9 million Americans are expected to shop this Friday, Saturday or Sunday, according to a survey conducted by BIGresearch for the National Retail Federation.

The federation estimates that holiday sales will climb 4.0 percent this year to $474.5 billion.
