There are some good parts of manchester, the outskirts, places like altrincham town center are usually quiet, occasionally some low-level to medium-level thuggery going on in and around the estates nearby. The navigation road area, especially the park, that attracts some proper knob'eads sometimes. Got stalked and chased by a big pack of fuckups round there, had to warn them off with the threat of having several containers of concentrated acid thrown in their face (I didn't end up actually doing so, but the sight and threat of the acid put them off, had my old man race up there in the car for an extraction of myself and the person with me)
And no, I don't usually carry acid around, I'd just bought it to restock after running out of H2SO4 and HCOOH and was in the process of going home, minding my own business, until I, and a (former, she turned out to be a real parasite and A-grade psycho-nitch fuckup) friend were on the way home, walking towards navigation metro stop, then got accosted by a dirty great crowd of pikey fuckwits, got followed, would almost certainly have got into a real ugly fight situation if it hadn't been for a bit of creativity on my part and managing to get a lift out of the area. We would have done a lot of damage to at least a few of them, think my (former) friend likely had her knife with her, and could have dropped a few in hand to hand, but there were too many of them for two people to take down, a couple of them were known hard-cases to boot. Not pretty either way.
