My geography needs and update........................ Douro portugal thinking it flows more north to south.
i was at the Coa Valley rock art, i could have driven a couple of minutes to be at the far end east core sone of Douro.

banging my had back in Salamanca. Yes I drove 2.5 hours for Coa Valley from here. I did also visit Almeida at 07:50 AM because portugal is -1 hours as Spain. And the ensamble with Rodriogo (all 3 places). 6 hours driving, 6 hours at the places. It's possible. But I regret the Douro, now the final one over there..........
