Writing a story based in a city I’ve never been in is interesting, and fun. I wonder how writers did it before the age of the internet. I can drop down into the streets and virtually walk them to get a feel for the city. I can look up bars and restaurants and read reviews and see pictures. Some even have virtual tours.
I have a feeling writers of the past had to be much more social than I do. They probably had to seek out people who’d been there and have conversations with them, pull out details, encourage descriptions of smells and sounds and ambiance.
Sounds like a lot of trouble!
