So disappointed in the Pen Llŷn episode - why on earth call it ‘the Llŷn Peninsula’ - it’s in Wales! If the Welsh made a programme in London would you be happy if we called it ‘Llundain’ - the Welsh word for London? I think not! And what on earth was the reference to the ‘Rivals’ mountains? Have some respect and use the proper names. Badly researched and very insulting - shame on you!
