My dad had one sparky. We would always take it river fishin and it was usually my job to carry it while my two older brothers fished. Usually the newspaper would be soaked by the time it was ready to cook lunch and of course it was always my fault we ate cold hotdogs
Come to think of it, I think that cooker may be at the bottom of the McKenzie river with my fishin pole when I slipped on a rock and floated down stream about 500 yards. I was probably 8 years old so 40 years ago. I used my 9 lives ages 8 thru 17
