Great share ! Nice and positive too.
Dung floors are still used in rural dwellings here in Sourh Africa.
And our farmer family had dung floors throughout their house on the farm in an area called Warmbaths.
May i assure you that there was no unpleasant odour once it was laid and had dried out - in fact it gave of a sweetish "planty" fragrance.
You then applied floor polish to it and of course it was warm in winter !
