I have been working in Wales
Wales tends to enthusiastically support their national teams while the only support for the team in white are typically the hooligans
Once a year, typically the last Saturday in April, the four Welsh Rugby Union teams play on Judgement day at the (former) Millennium stadium in Cardiff. £10 for two matches and all the Brains you can drink. This is after tailgating Welch style (hit as many pubs in downtown Cardiff as possible).
BTW, I tend to support the Ospreys.
Hm, sounds like a lot of fun. Hey at least you don't have to worry about customs and passports being re-instituted in Wales, at least not yet.
What is a Brain? A brand of beer I assume, or something harder?
And good luck with those Ospreys.
