The smell of a mopane fire. Every now & then I think I get a whiff & am transported in my mind right back there.
or

The hot dry earthy smell of a herd of cape buffalo, when you are sitting on your butt close enough to hear their stomachs gurgling & working and smoking a cigarette with them on 3 sides of you knowing it won't matter about the smoke cause if the breeze changes their gone in a flash & a cloud of dust anyway. Spike just grins & said "Now this is living , eh?"
