Years ago a guy drove a fine old about a 50 chev pickup to work. I asked him about it and he said it had been his dad`s back in Oklahoma. His dad was old and lived alone. He was driving to town on a brushy old gravel road, had a heart attack and run off the road. The brush had sprang back and it was like a week before he was found. I was polite and said nothing but he must have seen my quizzical look. He went on to say, aw, it aint bad, cleaned up good. When I turn the heater on ya might smell just a little something but it aint real bad.
Maybe thats why he always carried some sen sen with him.
