Track a white rhino on foot, together.
This is the moment most couples say they will remember for the rest of their lives. You leave the vehicle, drop your voice to a whisper, and walk into a landscape of boulders older than bacteria. Your guide reads spoor, wind and bird calls. Your armed ranger walks ahead.
And then — sometimes after twenty minutes, sometimes after two hours — the bush goes quiet, the guide raises a hand, and a two-tonne white rhino and her calf are standing thirty metres away, tearing grass. You do not move. You do not breathe. You hold hands and you understand, suddenly, why you came.
