hmm, surprised nothing from the Birmingham area showed up. One of the
densest areas of coverage in the db is centred on Sutton Coldfield (rather
than Birmingham itself). If it's a city issue, then none of the London
borough names below are cities anyway. Or am I missing something?

Nice work though,
