There is a real rivalry between the Welsh and English, sporting and otherwise. Kind of like the rivalry Canadians have of Americans (I'm sure that if Americans considered their Northern neighbors to be rivals in anything other than ice hockey that sentiment would be returned.) Regardless, there's a mutual tension between the English and Welsh.
My Ex was not fond of the Welsh and therefore never wanted to go to Wales, even though there are many lovely places within 3-4 hours of London to visit and explore. Being freed from that restriction I am now free to visit the country unencumbered by centuries of embedded baggage. I'd like to say that I went to one of the lovely beaches and hiked the beautiful peaks of Snowdonia.
So the good news is I still have plenty more to see in Wales in 2014 and beyond.
