Interesting that you should say Sahara sand. Where I am in Italy we've had "sandy" wind which has left all the outdoor surfaces and windows a murky dirty colour! Fantastic sky shot there, it's very atmospheric. Fav.
Looks like the whole place is on fire. Beautiful shot. Did you get any rain with it? When we have winds coming from over the Sahara and a slight downpour of rain, the cars will find themselves with fine sand and would need a good water shower.
