There is a checker for Northern California DeLorme but not for the whole state one. I can provide the per page coordinates needed to define the polygons. Since Northern California exists already, I'm hoping this would be easy to build from that. Is there an appetite for doing this?
I'm aware it would not be a full checker because the challenge does not allow finds used for Northern or Southern to be used with Golden State. Thus a user would need further checking but it would give them a good start or all they need if they are not attempting the Northern or Southern ones.
