Not only are you born with it, but you die with it. The loyalty never leaves you.
You can travel all over the world with it, and it's always with you. And you inevitably meet somebody, somewhere, who is "one of us". There are hordes of us in every state, north and south, east and west.
Some of us even live on the other side of the world, in another hemisphere, where it is summer during winter and winter during summer. Even here, in this far corner of the globe, I have met other Husker fans.
Those from a neighboring state like to point out that "it's because your state is so bleak and so boring, that that's all you got." What they fail to understand is that we're everywhere.
No matter where I go in the world, I'm always happy to call myself a Nebraskan, moreso than anything else, even though I've lived in other places for much longer periods of time.
