A couple of days ago I bought a used 2001 street atlas of London. I went through it quite often and was struck by the combination of narrow and sweeping structures throughout that metropolitan area. Places like Hampstead appear to be little villages with a subway station holding it together - that is what the map tells me. I have never been there. In fact I have never really been to London. But telling from the street atlas - and all the things you know about London - I am very excited to go. It’s definitively on my to-do list for the next couple of weeks. Then I can find out if the actual experience matches my imagination derived from the map.
