The mini bus we were driving from the Gambia across into Senegal, was not air conditioned, so the only way to keep cool was to have all the windows open. The roads are just dry, sandy tracks, which means that all the dust is blown into your vehicle.
By the time we reached the lodge in the evening after a full day's driving, we were absolutely covered in a layer of red sand. My T-shirt was white when I started that morning!
Approaching the fishing village by boat, we were told by the guide to not take any photos in the village of the local people as they were really quite hostile. We did not find the people here very friendly at all, and heeded the warning.
