It may be heresy, but I say go ice fishing. You can brew all year long, but only ice fish (it seems) 4 or 5 months a year. Besides, it's amusing to think that somewhere there's a Southerner asking, "When you say 'drive' onto the ice, you really mean 'walk', right?"
Brewing on the lake would give you *lots* of water for the chiller though.

Yes, that *is* beer. Water, malt, hops, and yeast mean it's beer. Go ahead and try a glass...
