There's nothing wrong with Grantham, apart from Maggie having been born there. It's just an ordinary market town - not particularly lovely, but not grim, either. It has a kind of parallel high street where all the shops are still owned by real people, which is nice. Good market. Some nice buildings and a twisty turny old bit that's quite charming.

It hasn't been gentrified, but then again, this is Lincolnshire.

Now Boston, on the other hand... *shudders*
