Poet Ifor ap Glyn is a man on a mission. His challenge? To journey round Wales using Welsh alone, but will he be successful in your area..?
Tregaron - 67.9% Welsh speakers in 2001
Llanymddyfri - 47% Welsh speakers in 2001
Aberhonddu - 14% Welsh speakers in 2001
This fourth programme sees Ifor, who was born and raised in London, retracing his Welsh heritage and returning to Pontrhydfendigaid, near Aberystwyth, where his great-grandfather, Thomas Hughes, worked as a drover.
A common vocation in those days, Thomas' work frequently took him down to London, but how successful will Ifor be as he embarks on a similar journey today - and who is his woolly travelling companion?!
