Gang, I hope you are rockin as we gear up for a nasty cold spell in the northeast. Over the past few months I've been burning wood from the same batch and have distinctly different results. The wood is three year old ash and white oak; half of it was moved under my sun porch 05/2012 (no rain exposure), and the other half sat exposed to good sun and wind but uncovered. Well, the half that was uncovered burns like concrete, even when I bring it inside a week before burning and let it dehumidify and warm up. The wood that was put under my sun room burns like a Roman Candle and is heating the house like no tomorrow. Your results may vary, but the upshot of this is that I'm going to buy sheets of metal roofing to keep rain off the stacks.
