Memories

I bought a bag of dolomite lime on line, delivered today, now really don't know if I purchased it for the garden, or because of the memories it re-kindles, when working in the local steelworks I must have shovelled tonnes of the stuff when fettling the furnaces, now I am wishing I had taken some bags of it, it would have lasted for years and saved me some money
Do you use anything in the garden which brings back memories
