So here we are almost at journey’s end. The last part of our trip takes us down the western side of Colombia and back to Bogota and then home! But it is so rich in experience that I’m splitting it into two blogs. We travel via a mix of plane and car, and see two extremes of this country – the very rich and the dirt poor and, in Medellin, some green shoots of transformation. Venezuelan refugees continue to be a major theme, always on the road – walking to who-knows-where, begging in the cities, sleeping rough. Depending who you talk to there are between two to three million of them. Some find work undercutting local labour, but most rely on generosity and handouts in this poorest of countries.
