Generally speaking, Wales is shit. Let's not beat about the bush, I think the country has a lower GDP than Albania or something. There's very little disposable income and most people are living beyond their means on finance. But as some have said, there are a few gems lurking around looking to supplement their benefits. It requires a patient, long-game approach.
As a massive contrast, I work in London, which has an Economic output greater than Sweden. Lots of cash around and some of the most beautiful civvy women I've ever seen. I'm stunned every day at some of the hotties that give me a smile - this has never happened in Wales, ever! Granted, most of these women aren't British but my todger doesn't seem to mind.
In my opinion the environment in London always gets you in the mood to get up to something sordid!
One plus about Cardiff is it's not too far from Bristol, which tends to have more than a few beauties. Punters should have a special card exempting them from paying the toll at the bridge though!
