Rowing for Pleasure has posted a picture a bit like the one above and I can guess why, as I stopped there too when walking with the Natural Navigator.
You might not be too surprised to discover that the explanation involves a pub, namely The Black Rabbit that occupies this picturesque corner of the Arun river. It's a great location but I've heard a few bad stories of slow service and poor value for money.
Continuing the gastro theme, there is good news for any ex-Cambridge sailors out there (yes Tillerman I mean you) in that the famous Fitzbillies Chelsea Bun might be making a return.
Fingers crossed that next trip up there I'll be able to enjoy that sticky, gooey delicacy.
