While the Castle will likely be closed until they get firm lines established, it appears the fire is taking a north by northwest move so confidence is pretty high that there will be no fight to save it. I listened in on the air tankers last night as they connected retardant lines in the castle vicinity as their last job before heading to base. The overnight IR runs showed only minimal advance on those areas and very few intense heat areas.
