A normal part of life in Nairobi is smoke. This may be huge quantities of diesel, belching from any number of vehicles -- or in this case, burning branches and leaves. I prefer the latter!
It’s a lot cheaper to burn that stuff than pay for someone to haul it off.
And yes, this was on my walk home from work, yesterday. Once again, it’s odd that there are just those two ladies in the shot. (Maybe everyone gets shy when I whip out the camera.)
