Salford is similar. I live in Eccles and there's a few old buildings. One is the Bridgewater mill. It's a big dirty building that's been converted into a business unit. I remember I used to go to a gym in there.
Salford is apparently the most poluted area in the UK today. There's no smog but as you move further out towards Cheshire / Warrington, like Irlam and Cadishead, it's a world apart.
