Here in the southern Wisconsin-northern Illinois area there is salt available. But the prices have got insane. Our streets dept. locked in this spring, took delivery and paid late summer and got it at around $46 per ton. With the price volatility the vendors won't honor prices for delayed delivery. If you want some now you will see quotes well over $200 per ton, I have heard as high as $250. We have cut back the salt by combining salt crystal with brine and beet juice. Sounds goofy and the pavement does take on a red tinge but it keeps the ice from buidling up or sticking and saves money.
