One thing Seattle and San Francisco do have in common is a love of beer. Much like the '12th Man Pale Ale' being brewed in Western Washington, 49ers fans have come up with a 'Niner Nation IPA'.
Josh Leavy, with San Francisco Brewing Company, says he came up with the idea not long after the 49ers beat the Green Bay Packers.
Ever since, he says the beer has been doing big business in the bay area. He brewed another big batch on Saturday and is hoping to drink and sell it, all the way to the Super Bowl.
"I already booked my ticket to New York," Leavy said. "Whether they go or not, I'll still be there, I'm a football fan. So whatever team goes, I'll still support, but if it's Seattle, I'll definitely be on the other side."
Leavy says the 'Niner Nation IPA' is not yet available outside of San Francisco. Most Seahawks fans would probably say that's for the best.
