At a place i used to live they had all the fencing renewed, it took me 14 months to burn the old posts in my woodburner and a heck of a lot of chainsaw sharpening. I shut it down at night and in the morning opened the vents and it was still in. I got abit carried away at one point and it got that hot i could feel the heat from the kitchen sink, 25 feet away and you couldn't get withing 8 foot of the fire the water tank started banging so loudly i thought someone was breaking in Just to say...if you see any there great fuel.
