I am hoping to get a wood stove to use for outside canning. I know where a couple are in junked state right now and am just waiting to find the house to see about hauling one off. But, you are right, kerosene is a great storing fuel, we have a large heater here for emergencies. After looking at that website I think I'm going to have to see if I can't rig some cooking on the one we have. I hadn't thought of it before.
Most of my adult life I lived without air conditioning in the house. and I agree with you about canning in summer. It was hot! I always got the kids one of those 18" deep WalMart pools in summer to keep cool, I'd go out and dunk in the pool in the middle of canning with my clothes on just to cool off. I was in my 20's and early 30's then. I think the heat would get to me even worse like that now. LOL hot flashes donchaknow.
How are you getting all that produce to can this time of year? From my 11 years living in North Central Texas, I learned that there was just a barbed wire fence between TX and the North Pole, and that was only one strand which enhanced those Blue Northers. Of course the offset was 50's and 60's or more a few days later.
