KENOSHA, Wis. (CBS) -- At the Brat Stop in Kenosha, the outside color scheme -- green and gold -- gives away the owner's allegiance.

So does the noose around the neck of a gigantic plaster Bear, wearing a replica of Hall-of-Famer Mike Singletary's jersey.

Jerry Rasmussen loves the Packers, but among his customers, he estimates it's a 60-40 split for the Bears.

Yes, it's Wisconsin, but Kenosha is close to Chicago, right on the Wisconsin-Illinois border. It's fertile ground for an intense rivalry, the longest in NFL history.

"This is what you call the border wars up here," Bob Wagner, who lives in Wisconsin, told CBS 2's Jim Williams. "Lot of Bear fans, lot of Packer fans."

"There's a lot of hatred … Real hatred," Packer fan David Sequist said.

The rivalry is fueled by two games a year, over many decades and more than 170 meetings altogether.

Aaron Bruno-Lewys, who likes the Bears, plans to trash talk with this friends "all week, all day, actually for the rest of the year as well."

It'll be inflamed on the campus of Marquette University in Milwaukee, where Chicagoan Mary-Kate Daniher is headed after winter break.

"It seems split evenly. They (the fans) don't like each other," Daniher.
