A friend was remembering his visit to Ty Mari almost 50 years ago when we started up the self-catering business. His stand-out memory was that of stunning night skies. He would be so pleased to know of the wonderful developments with the local dark sky park. I welcome the recognition that the Cambrian Mountains offer some of the best dark skies in the UK. The picture of Ty Mari, Welsh Hideaways, taken on a clear night emphasises the glory of the night sky.
