I some times wish that Cape Town had an underground metro. Wouldn't it be great to catch the underground from the city center to Sea Point, then across the Waterfront and back to your apartment in Gardens?
Thinking about the large amount of granite that we'd have to excavate and the huge amounts of ground water that we'd have to contend with I guess it would cost far too much money to build one, and our best bet would be a monorail (like one that we traveled on in Sydney).
