My dad retired from work many years ago, but back then one of the things that he use to do was inspect the harbour cranes to ensure that they were kept in a good working condition. He use to climb to the end of the jib (the part right at the end of the arm from where the cable extends downwards) in all kinds of weather. If you're familiar with Cape Town's weather you'll know that this would mean that on occasion he'd climb out there in high winds and even rainy weather - and apparently, even tough the cranes may look perfectly stable from the ground, when you're up there they bob about a bit like a rodeo bull!
