Always looking for alternative heat source....the pioneers who traveled across the US use buffalo chips, the industrial revolution broght coal, the GreatDepression brought dams....and the 70s,,, well it brought cans of sterno....the emgerncy back-up found in every cupboard.....that served no purpose...other than cooking ramen noodles over the waxy solid in an alumincan can. But with the package, they were lucky, for few folks had matches to light candles or sterno cans in the deptsh of the basement. luck was their partner, as the book of matches, the only matches in the house, came from the casino....
