I've straightened the photo a bit but I think that the slant of the viaduct is due to perspective. It was once used by a little train carrying potatoes to the city. Yes, nature is waking up, the birds are singing and the frogs love songs are deathening (but cheerful). Pollen flies everywhere and makes me sneeze, which adds to the musical atmosphere.

Nowadays, mules and donkeys. But they cannot cross the river. At this place, the bags of potatoes are stacked on a canoe. On the other side of the river, the farm workers make a chain which goes to the city, throwing the bags to eachother. Hard work, low pay...

Just kidding... Nowadays trucks replace train transportation. More pollution but more competitiveness, as they say

Well well, that's what I remembered reading your reply... I could carry a couple of Lipton's tea bags on my head, but no more.
