I've read that it wouldn't take much for propane prices to go sky high once again this winter or the next. They say that exports continue to increase since other lands are willing to pay more for the fuel and new ports needed to fill tankers are now built and are busy. Also some pipelines have been converted to other fuels and reversed. I don't know much about that... Another factor is the price of dry corn. It pays to dry it and sell instead of storing it and letting it dry naturally while waiting for the price to rise. I had my tank filled for the year today at $1.529 for 380 gallons. Not bad considering what last winters prices were and with that plus my wood I'll be warm this winter.
