Someone mentioned Fallin earlier - I used to spend a bit of time there, and it seemed a decent enough place to live, especially as Stirling town centre is within walking distance. Bit miserable if you're an auld yin though, I'd have thought. Plean was a different matter - miserable hellhole with constant running neighbourhood battles and weans breaking everything, along with the worst chippy I've ever been in, where they seemed to have cooked everything the day before. I see they've built lots of new housing in the last decade, and it looked a bit nicer last time I passed through.
I've lived in both Alloa and Sauchie, and both are nice quiet wee places to live, assuming you're happy to travel through to Stirling or Falkirk for entertainment. Tullibody's a different matter, or was when I spent more time there, ten or fifteen years ago. It's just housing, a pub, and a chippy. Oh, and the Tron Court shopping area, which was entirely derelict when last I saw it, barring three shops. And one of them was an empty hole that someone had parked a few arcade machines in (of the Super Sprint vintage).
I'd like to think that Tron Court would be a bustling, vibrant shopping area by now, purely for the local community's sanity.
