Rolf’s latest travel project is the No Baggage Challenge — a journey that will take him around the world without using a single piece of luggage. Every few days, we’ll be updating Vagabonding with a recap of the latest to keep you up to date on the adventure.

Rolf spent a few days off the grid while on safari in Kruger National Park. While there, he created his own personal alternative list to the Big Five animals — top of the list: hipppos. After the safari, they headed to the Welgevonden Game Preserve, three hours northwest of Johannesburg — where they had the opportunity to sample some world-class elephant-dung tea, before flying to Bangkok.

“Of all the things I’d expected to experience when planning my no-luggage world journey, drinking elephant-dung tea in South Africa was not among them. I’d expected I might explore nightlife in Spain (which I did, while eating tapas in Madrid) or ride a camel in Egypt (which I did, at Giza) — and I even thought I’d get lost from time to time (which I did in Morocco, among other places) — but I never expected to imbibe a medicinal beverage that had recently passed through an elephant’s ass. Such is is the unpredictability of travel.” –Rolf on Justin’s elephant-poop cold remedy
