Right, a different perspective.
Anti English banter is no worse than any anti Scots banter I have encountered down south. That’s to say, tedious pish from the mouths of tedious **** trying to be funny rather than with any real malice. That said I tend not to hang around the real shiteholes so YMMV.
Ayrshire isn’t that bad depending on where you go, the East is mainly shite aside from the village’s north of Kilmarnock, the rest is mainly forgotten ex mining villages. If you want an idea read the early chapters of The Flying Scotsman. North, again, isn’t all that. I stay on Largs which, although nice is mostly populated by knobends. South is much better in terms of places to live and the people (I may be biased coming from Troon).
Not much experience of D&G in terms of Solway firth but I will say this; I don’t see the big attraction. My friend’s folks have retired in Elrig and its lovely but closest town is Newton Stewart then Stranraer for the train. That said its in a nice quiet part of the world and I could happily live there.
In contrast Castle Douglas has nothing. As in, its big enough to be a town but nothing to offer that it should for a town that size. I can imagine it would be easy to get frustrated with it. I should add that this is just based on a brief stay but have seen plenty of better places. Oh, and depending where you are you could be talking an 80odd mile round trip to Dumfries, don’t even entertain notions of public transport.
