We wonder why Wales is poor af when people can't even get to work

I'm curious as to how a French wine festival made its way to Swansea. Is there any particular link between the city/Wales and the Beaujolais wine region?

Hi! I hope this is the right subreddit to ask, so I stumbled across this song and I have searched everywhere and can't find any lyrics to it. I love this song, and this band and would like to know what it is I am attempting to sing along with. Could anyone help with a translation or even a rough transcript of the lyrics? Diolch ymlaen llaw!

Helô! My friends and I are currently researching Welsh swearwords. We're looking for adult speakers and learners of Welsh who swear both in Welsh and English. If you have the time and you fit the description, we'd be very thankful if you could fill in our questionnaire. It comes in two parts (closed and open questions). We offer it both in English and Welsh, so choose whichever version you prefer. Diolch yn fawr!

Does this line like have many delays or is it pretty good and is their anything I should keep in mind as it's my first time doing this route on the 10th and coming back on the 11th of December (Coming from and back to Bridgwater) and never been on a Tfw train before.

Hello. I've noticed that in Wales the Rights of Way (footpaths etc) aren't signposted and loads of obstructions/hedges etc. I'm not talking about touristy areas, just general farmland. I know where the Rights of Way should be as I'm referring to a map. Has anyone attempted to walk along them and did it result in any trouble such as a load of pellets in your arse?

Sorry for the vent but after months and months of disruption on the Treherbert line (bus replacements, closures etc.) and still no bloody Metro last night was just the final straw! Got the 17:59 to Treherbert, prolonged wait at Pontypridd and then told not stopping until Ystrad. Loads of people had to get off and wait for the next train. Then got to Ton Pentre to be told this was as far as they were going and we’d have to wait for the next train….which yes, you guessed it was cancelled. Had to walk the rest of the way home in the dark on a Friday night. I’m a lone female. How can they think this is okay? I’m buying a car. I’m done with them.
