Just stuck a pin in Durham and now I have a question for the techies amongst you.
Being security wise, I put the post code of a local landmark in, which is near enough to where I live without disclosing my actual street name, however when I checked it, the balloon was directly in my street !
After deleting that one, I replaced the post code with a truncated one and it ended up at my previous street where my girlfriend (now wife) lived 7 or 8 years ago, when I first moved in with her.
Someone please tell me that's not just coincidence
