Mr Shark tried for this one two weeks ago after much rain and found the ditch very wet and the cap's divot full of water. Bailing it out would have been fruitless. Today conditions were much drier but the water had deposited a layer of silt in the hole. A disposable cup picked up at his previous stop and a bit of drinking water came in handy to clean off the cap.
Thanks for a cap along the way today.
