Change of seasons in the desert

Autumn is nearly over here in the sandpit. Soon our air conditioners will be switched over to heaters to warm the cold tiled buildings. Pupils are now wearing winter uniforms to school and the International Award expeditions begin this weekend (it always rains during the Bronze desert hike!).

First world signs in a developing country.
