In the burbs of Atlanta we had for heat
1- Coal w/pot belly stove but I barely remember it. Used to find pieces of coal and the spent ones in the yard when I played outside.
2- LP gas with just a few small heaters that was turned 100% off at night and restarted in the morning. (no pilor lights on these boys)
3- Natural gas with one big heater. Turned off at night and cut on in the morning. If it got really really cold they would leave it on very very low.
I do remember my Grandpa's General store with a big old pot belly stove and the old men huddling around it. I used to love to spit on it to hear the sizzzzzzzzzzle. And of course many of the farmers we knew had fireplaces only.
Gosh I am old. Anybody got a pot bellied stove for me to huddle around this winter?
