Went and checked the charcoal.
it was still glowing embers on ome charcoal, so i covered it over again and left it.
The airducts are fully closed and the pit is burried.
There is a fair amount of charcoal in the pit now, and it should be a good haul.
it will be thursday before i get back to it.
HUzzah! an end to my compusive thoughts on charcoal may come to an end.. soon..
