Sitting here in Nebraska, diesel is gelled even with additive. It's like frickin -23 without the wind chill. The furnace isn't really shutting off anymore. Thank god for natural gas, cause the city said yesterday they're going to have rolling blackouts now because the grid is overloaded. I have a generator in the basement hooked straight to a 500 gallon propane tank and it's the first time I'm ever really going to need it.
