Personal highlights

1. Tunnel Tours: fun group of guides showing us Cape Town's underground
2. Castle of Good Hope: old fortress to defend the city against any intruders
3. Coincidence: joining a private tour of a random group on a day with a military parade
4. Underground: wading with regular street shoes through tunnels with flowing water
5. Water: wasting endless streams of clean fresh water in a time of absolute drought
