That dieselly, oily, smell of railroad trains, because it always reminds me of my Dad who worked for a railroad, and Cashmere Bouquet soap, which always reminds me of my uncle and godfather who died in 1955.
I was just thinking of this the other day. I was walking to class and the people on campus were leaf-blowing. The mix of the leaves and the small gas engine's exhaust were intoxicating. Then, I thought of how weird it was to like such smell. At least now I'm not the only one !
