Yes!!!!!
I don't live too far from Laugharne, so I've been to see Dylan Thomas's boathouse many times. And, of course, have had a glass of whisky at Brown's, his local pub. Oh, and Virginia Woolf spent a couple of holidays here in my village - staying in the upstairs of a house that now belongs to a friend of mine. She is supposed to have written
The Waves here.
In the US, my mother and I often planned autumn trips to see various literary sites - usually in conjunction with some leaf-peeping. Edith Wharton, Louisa May Alcott, etc. And, as a child, I was dragged around every house Charles Dickens ever lived in in London!
The pub in Penzance that appears in the opening chapter of Treasure Island?
I didn't know about that one!! But, since I spend a lot of time in Cornwall, I'll have to check it out. We've done all the Daphe du Maurier, John Betjeman and Virginia Woolf stuff. There are also lots of Brontë (Branwell) connections in Penzance - when he was a child, my boyfriend used to live in the Brontës' uncle's house!
