The whole area around Wałbrzych (especially the villages that are at the bottom of the hills) are exceptionally depressing
I was on a bus from Wrocław to Bielawa once (we have family friends there), and it reminded me of the time I once caught an overnight National Express coach from Leeds to London (this was a long time ago, when I was a poor student - I'd fly now. Or, I would if bmi hadn't cancelled the service, lol. Then again, I have no reason to go to Leeds, but I'm sure you see my rather waffly point. haha).
The coach stopped at some Midlands dump (Chesterfield, I think) - one of those places where one person gets on, and no-one gets off. Just like when the bus pulled up in Wałbrzych, lol :D
However, despite all this, there is still money to be made, even in these depressing places - the aforementioned family friends have made a fortune from running pharmacies and dry cleaners around Bielawa/Wałbrzych. I've never seen a house like theirs in my life, amazing.
