I’m popping off to Ethiopia, but enjoy a riveting spring

It seems that, by the time you read this column, I’ll be in the Ethiopian highlands or lowlands, maybe in the Rift Valley. I have no special plans or itinerary. I’ve never been in Ethiopia before.
It’s very high above sea-level and I hope my ears don’t keep popping all the time. They have a tendency to do, even in La Gomera, where the highest point is only 1,4870m.
