'you'll realise it's quite small really and get to know the place.'

I've been here for ~10 years and feel like I'm familiar with a fairly narrow slice of it (mostly north/north east a little bit). A good mental model imo is to see it as a collection of smaller towns, each with distinct urban centres, that have grown into each other. This makes it endlessly interesting to me and I feel like I'm unlocking new parts of it all the time.
