Funny how you fail to realise what's up your snout. I lived here for 20odd years before moving to the Big Smoke. Its full of posh university "ya's" (audible from some distance) but also many characterful townsfolk with a tale to tell (and not always about mines)
Which side do you sit?
A nightout is full-on but what you experience depends upon which side of Town you venture. I recently started off with the university crowded bars near the Cathedral (I did feel old and lacking a Dr Who scarf) then advanced to North Road where it is considerably/dangerously lively. You don't have to get wrecked and have a fight but it helps.
Police presence is strong so don't worry if female.
Another amazing night out is Newcastle, but thats another blog.
