Friday, 8 August. I leave the Warren Cottage after 4am. It is dark and windy and rain is pouring down on me. By the time I reach the blocks I know that my clothes - supposed to be weather-proof - aren't waterproof at all.
By 5am I have tied the yellow blocks to the fixings prepared the previous day.
The yellow glows in the twilight and when the rain stops the changing light makes me forget that I am wet to the skin.
The plan was to start filming at 6am when the water reached the blocks. However at six a thick cloud was shedding its cargo again into the wind. No good conditions for Jo's precious video camera... Sheltered in the car we waited for better times.
Finally, by 7:30 filming started. The northeasterly wind brought in the tide fast.
Agitated North Sea - and bitterly cold air in mid summer.
40 minutes later all the defence blocks had almost disappeared.
And within the next hour - while the light and atmosphere were changing constantly - all the yellow blocks, one by one, swam ashore.
