My husband, Bob, and I were on a two week bus tour through England, Scotland and Wales. But we were in Wales vely briefly. We stopped for lunch in the lovely little town of Llangolion and I tried their rum baba, served by a very pleasant young woman.
Our tour guide, Tristan, had done a lot of hiking and camping in England, where one can freely cross the farmers lands without any fear. It is the custom that most land is ~~open~~ to the public, as long as they don't leave trash behind. However, he warned us that hiking and camping in Wales was a little risky, if one goes far back in the hills. As he said, as in parts of Appalacha in the U.S., some people have been back in the Welsh hills for such a long time, isolated from the rest of the world, there has been inbreeding and the gene pool has gone down in intelligence. Couple a low intelligence with their distrust of strangers, for one's own safety, it is wise to avoid the Welsh mountains.
