It would be reasonable to think Charlie was feeling a touch of heatstroke, for he and Ben spent 2d each on the Barmouth Railway viaduct footbridge, a place they could have avoided with some elementary planning.  But he does say the view from the bridge is worth it.  We get for free a lesson in Welsh name pronunciation and further instruction on where to practice.  And something new for us all, the Lake of Three Pebbles, on the summit of the Tal-y-Llyn Pass.
