about 10 yrs ago we went to the SCG and were surprised,but pleased we could use our brollies. However, apart from the run off from others sitting near us (as Shane mentioned), even when the rain stopped we needed to keep them up as there was run off from the roof. Luckily there was a walkway directly behind us so we weren't blocking anyone's views - apart from a few toffs behind the glass panel in the corporate boxes
