Actually Sticks, this topic has got me thinking back many , many years.
My Grandpa died when I was four and after his death his Greeanhoeuse went to 'rack and ruin' untill all th glass was gone and just the brick trenches full of soil was left. If I ran my fingers through the soil I could smell the tomatoes that he use to grow.
NOW , whenever I smell tomatoes on the vine or growing in a greenhouse I am trasported back to those halcion days when I was a child.
