Quad biking in NamibiaThe laminated computer printout on the shop wall claims they have hosted Brangelina multiple times on their ATVs, which they have proudly named after these guests (or they say). A 2-hour quad bike ride through the white sand dunes of Swakopmund, each one sandwiching a 60-minute break sand-boarding down the taller-than-they-seem dunes. 4 runs at 15-minutes each to walk back up, breathlessly panting for breath in the hot sun, sweat soaking through your clothes. Awesomeness!!
