A lot easier and less terrifying than I expected! Althogh we had on all the kit, once you got used to what was going on it was all a breeze. Probably didn't hurt that it was a nice day and not too windy.
Another group managed to catch an errant balloon that floated past them - quite the achievement, although it did seem to concern our guide a little. He though they had managed to smuggle it up there!
Great views, and learnt a lot about the history of the bridge itself. Including the fact that it's twice the height of the nearby Opera House.
