Very interesting, thank you for sharing. I've never seen this before. And I also find it very interesting that according to the map, no search has been done at or near Oviedo. Wasn't that the place that was mentioned that was a future potential place for her to be living? If so, it would seem that would be within her "comfort zone" as Tim put it. If she were planning on moving there eventually (and I could be totally wrong about that), it might make sense that she might be there, since KC stated that she felt she was "close".
I am off to search where Oviedo came up. I thought it was in conversations with her and Amy and a house there, which is also where GA said he was going to "search" that one day, with his billboard in tow.
