Less,
I would think from your posts on "stinky" snowmobiles that you were against polluting the environment. Just think of the pollution from power plant emissions running your bubbler 24/7 creates. A much better solution would be for you to go to Wal-Mart and buy a hand operated ice chopper. You could go to your dock every few hours in the really cold weather and chop away. Think of the needless pollution you would prevent and the extra calories you would burn keeping you fit and trim. Yeah, just like walking through the woods in deep snow……
