Aurora peaks in December, as does Comet ISON: what to wear?

Orion, where in the south are you going? The darkest skies we have found are in Utah near Bryce, but that is kind of far from Victoria! What about eastern Oregon?

And if we are still foolish enough to try to combine the aurora with the comet, where would we be most likely to find clear skies in December?? Maybe northern Alberta? I have no clue.
