In temperature..not a swing like a tire swing. Trying to capture some info on my highly technical gear. Below 0 most of the day and we are still burning softwood..want to see the difference it makes on a similar weather day when burning hardwood. The pictures are 1st – hometime, 2nd – outside, 3rd – inside after 3 hours. The upper 3 are c and the lower are f ( for those (me included) who are f to c ignant. Yes I spelled ignorant wrong. Hehe.
