I loved the museum in Bath, because of the hilarious Mr. Darcy portraits everywhere. And how nice it is to go to the city, see the sights, look at the baths, and have something to eat with knowledge that people have done exactly that for a thousand years?
For anyone who wishes there were more Jane Austen books, I want to recommend Margaret Oliphant. She's a generation later, but her books are kind of the same - young women working out their place in the world. And because she's a bit later, her young ladies have a little bit, um, mouthier? She's very funny.
