I'm from England and have a fair idea of where places are and what they feel like when you get there, but I'd still love to see a map of the whole area with pins marking the main things you cover in the podcasts. It would end up an illegible pin cushion pretty quickly if you put everything on there, but at least the main events/themes would be very helpful. Or maybe a different map for every 50 podcasts or every chunk of history, split it as you will. Ideally the pins on the map would reference the podcast episode number that talks about that place, although that's probably lots of work. Still, it would be nice.
