July 2013: It was like pea soup out there this morning with the visibility getting down  to a few metres. Lucky I know my way around or you could find yourself going  round in circles. You have to have you wits about you when the conditions are like this, as you  have to be extremely aware of the sculls. They row 10 deep from the embankment  and move with lighting speed. The last thing you want to do is be T-boned by a  scud scull that suddenly appears from the fog.
