The Mystery, Crime, and Thriller Group discussion

As many of the scenes from "Run From The Devil" take place in real world locations, I decided to post photos of those places? Not a lot of thought went into this decision. I just happened to be cycling along the section of coast near where one character's parents live (in the book, folks! In the book!). So, I posted some photos showing the views across the Bay from the windows and terrace of this fictional house on my blog. Now I'm thinking that I'll post pics and maps relating to different events and scenes.
My question is, do people think that this would be helpful? Interesting? Useful? OR a dumb spoiler move?

I personally think it would be more of a hobby thing and some people would find it interesting. Maybe you could put a potential spoiler warning?
