This is my contribution to Cee’s Fun Foto Challenge: Sense of Smelling.
I was stuck for an idea for the prompt until remembering a comment someone made on Facebook after I had posted a photo of a moto cross bike from the 1970s. The comment was about the distinctive smell from a lot of racing engine’s in those days.
It was the smell of Castrol R, an oil that contained a percentage of Castor seed oil giving a very distinctive smell to the exhaust fumes.
A couple of photos from my local moto cross circuit in the late 1970s, Hatherton near Nantwich in southern Cheshire.
