I've cooked over a red oak fire, but never used it in my smoker. When first split it has a rather strong, almost urine like smell. I bought some up near Tallulah falls and carried it back to our tent-site at Stone Mountain inside the van. The family was not very pleased with the smell, but the food tasted great.
