So, last week when we got on the Niokolo bus from Kédougou to Dakar, a very nice man sitting in the row behind us handed over these disposable surgical masks and told us to put them on. We weren't totally sure we would need them (the bus had windows and everything) but dutifully put them on anyway. (Left to right: me, Leah, Marielle, and New Ian.)
Four hours later when we stopped in Tamba we were very glad we'd done so.
Eight hours after that we were in Dakar, enjoying croissants and fancy coffees and attracting all sorts of sidelong looks from the well-kempt people on their way to work. (Once the Peace Corps office was open for business we went and took showers and felt much more presentable.)
