Late last March I cut up this ash tree which had been down for a year or so ....I believe. It was split and stacked on pallets soon after, allowed to season without cover, and then moved into the wood shed. I was concerned it would not have enough time to season, but I was surprised just how light it was while moving it into the wood shed. It's burning very well, but when I start a fire there seems to be water bubbles on the ends for a couple of minutes. When the fire gets going and coals up I'll add more wood but there are no water bubbles. Has anyone experience this?
