Setting, get a map. #nanowrimo #writing

As I am putting details together for this new project, I realize I haven't quite figured out the setting. I know it is a semi rural area, but I am not sure I want to keep it in Oregon.
One thing I know once I settle on the location I will get myself a map or at least google map it and the surrounding area.
Another thought, do you use local landmarks in your writing? Again, map it. I have read stories where landmarks are used but then the remaining scenery isn't verfied. I guess I am a stickler for details like that, even in fiction.
