A question for the green-and-gold

Who are your biggest rivals, the Chicago Bears or the Minnesota Vikings? I ask because while I know the Bears rivalry has a much longer lineage and is usually brought up by the media, nearly every Packer fan I’ve ever met is obsessed with beating the Vikings and not much more concerned about the Bears than the Lions. The Lions have been around a lot longer than the Vikings, after all, and no one in the NFC Central cares about them.

Is this just a western Wisconsin phenomenon due to proximity?
