For a nice aroma, you need to mix in some good old New Mexico pinon pine, @Dizzy can confirm. Many years ago I broke a leaf on one of my rear springs when I used my almost new '84 FJ60 to haul a few loads of green pinon from the National Forest just north of town. I didn't own a trailer back then, or a pickup.Yeah, all winter. I try my hardest to not run the furnace.
I might run it once or twice a year to knock the chill off in the morning, after that it gets turned off.
Wood is basically free.
