I was up Victoria Park shooting with clients last week, when by chance workmen arrived for maintenance on pylons near where we were photographing. We were all fascinated with the ease with which they attended to their task.
Goodness, all of us quivered at the thought of climbing the spikes, let alone actually working at heights, with high voltage. I guess this is what they do, and receive training for. Nevertheless, is not for everyone. This was on a nice day, and all credit to field workers heading off in stormy conditions when the rest of us rely on that power to keep our heaters on.
