What I remembered as being “Trash and Treasure with produce market” is now “Produce Market with trash and treasure”, not a lot of use to me but plenty of takers. Lots of specialist growers / sellers, last time I saw a market stall that only sold kang-kang was just outside Hoi An, in Vietnam. You can probably get any variety of potato that is currently a must. Lots of people having a very fine time.
