City in southern Derbyshire, England, UK, although not governed as part of that county. Population about 225 000. Historically always played second fiddle to larger and more glamourous (well, larger anyhow) Nottingham, 20km (12 miles) away. Home to the University of Derby, an institution best avoided if you want to maximise your career prospects. Nightlife not bad, but too many pubs.
Seven years after arriving, I have yet to leave. Still not sure why.
Note to non-Brits: Derby is pronounced "Darby". There is a reason for this, but I can't be arsed to explain.
