We had a bonfire but did not have marshmallows to toast for a snack. When the fire had burned down, Dancer wrapped up some potatoes in aluminum foil, two layers, and we threw them in the fire. Dad shoveled some hot coals on top of them and we sat for another half hour longer. We kept inching towards the fire as it was really cold out and without a blaze it was non to warm sitting in our plastic lawn chairs.
After a half hour, we pulled them out of the coals with tongs and went in the house to unwrap them to see what we got.
