I’ve used Pinterest for the last couple of books to collect my visual reference material. It’s been very, very handy. They just added a feature today where you can pin the locations to a map. I’d been trying to do that with Google Maps, but having the pictures and my notes all in one place is amazingly useful.
Also, a total time-sink, since I just mapped the locations in Without a Summer, which is already a published book BUT it was a good test.
I think this is really a brilliant idea! I hope you will continue to do this and that other authors will do that also
