Made it through the Sahara to Senegal. The trip was difficult and frequently uncomfortable (did you know there's an entire country with no shade?), but more or less within reasonable limits of risk. More details soon!
In the meantime, Juliette and I are enjoying the simple pleasures of running water and fresh vegetables, as well as the more luxurious pleasure of beaucoups mangos. I'm learning French really badly, and eating fish in spite of intending to avoid causing harm to living creatures.
