With Bill's help, we took the dinghy over to the footpath across Orford Ness. 'Treasures' included sunglasses, artificial flowers, self-heating 'Rocket Fuel' and an asthma inhaler...
The Ness - an SSSI (site of special scientific interest) - is also where I find most pens and pencils and a seemingly inexhaustible supply of burnt bottles and broken glass.
