A certain smell that brings back happy memories is the smell of diesel. This is my memory smell because it was the smell of my grandfather’s tractor. I can remember stepping out of the farm house, on to the cold patio, then into the soft grass with sandals and I would go for a ride in the tractor. We used to ride in the tractor all the way down to a lake. The engine would roar like thunder when it started and we went fast enough that a calm breeze would blow through my hair. I have not been to my Poppy’s farm in a very long time but once the scent of diesel shows up, it drags me back to the wonderful times I had with him.
