I recently came across Margot Flügel-Anhalt, who at almost 70, travels 22.000 km from Germany to Pakistan in the simplest of cars to see Nanga Parbat with her own two eyes.
With an open mind, an open heart and a desire to live life to the fullest, she truly embodies the spirit of overland travel to me.
You can use the automatic translation feature of youtube if german is not your thing. Highly recommended!
