I'm getting far too old for all this nonsense of scrabbling about in rivers, trying to walk in the river on slippery rocks and not drop the tripod and the camera, sitting on wet stone and getting all one's, ... er um, bits ...and everything else soaking wet. Effectively sitting in flowing water. And then it starts raining! And then you get home and realise what an absolutely wonderful few hours you've had.
