Don't know what all the fuss surrounding Moston is all about TBH. My Grandparents have lived there for over 40 years now, never been burgled, never been mugged, never really had any hassle. They also go round Harpurhey pretty much everyday and nothing has ever happend there either.
Same applies to Gorton where I grew up. As long as you know people there, it's a quality place to live.
So stop jumping on the Harpurhey is shit bandwagon. If you intend to avoid trouble then you will, if you don't, you wont.
