I was warned by our tour guide not to venture into the “dangerous” neighborhood of Havana’s central market, the Mercado de Cuatro Caminos. Too late! I’d already been there earlier in the day. And mucho happy that I had been. No other tourists around. Just Habaneros doing their daily shopping from whatever happened to be available that day. If the truck arrived with a certain kind of produce, it was up for sale. If not, not. Potatoes, I was told, only make a rare appearance here. Look at that great old scale!
