Book-ended by water

   An odd title for a post perhaps but our trip to Brecon was rather topped and tailed by water - in the form of reservoirs and a waterfall, and that's to forget the Monmouthshire and Brecon Canal.  The reservoirs are at Crai and Talybont (with its slightly sinister buildings), the waterfall, in the Vale of Neath, is at Aberdulais and is owned now by the National Trust.  Aberdulais was a favourite of Romantic painters such as Turner, but such admiration didn't prevent it being turned into a tin works in the 19th century.
