Still, it’s not all bad. The Health and Safety course I’m on is taught by an ex-military man, who retains the forces ethos of knocking off early as long as the work is done. We’re finished by 3.00 pm each day, so by 3.30 I’m enjoying the sunshine and a pint of Wensleydale Brewery‘s Semer Water ale at the Bolton Arms, Leyburn, in the gorgeous Yorkshire Dales.
