I’ve hear it said that there’s nothing as powerful as the sense of smell to carry us back to a moment or a place we haven’t thought about in years. I had one of those moments a few minutes ago. In smelling the combination of fresh-cut grass and the exhaust of a not-quite tuned gas engine, I was hit with an overwhelming recollection of my grandfather and his Allis Chalmers B-10 lawn tractor. I don’t think my grandfather was ever happier then when he was tooling around the yard on that mid-60s vintage machine. With that smell hanging in the air, for just a second, I was a kid again and could see people and places I haven’t set eyes on in twenty years. It was really quite remarkable and, I’m not too proud to say, it choked me up there for a minute. Memory is a funny thing like that.
