I live in New Iberia, near the Jefferson Island salt dome. You may remember a few years ago Texaco drilled a well that penetrated the salt mine and emptied the lake into the mine.
I posted some pictures over on the Inground forum that you may want to see. It didnt make it down to the predicted 23-degree low. Still the 26-degree low that we received was enough to worry about.
