I don't think this has been announced yet, but I read something about the upcoming elections that made me think a piece of info has slipped out. On this page:
it shows that Mark Austin is the Chairman for Kentucky. There's never been a rally in KY. But then I read this post by Chuck Manley:
and he's indicating that the 2015 rally will be in Zone II or the Mountain States. A rally in Kentucky would be Zone III again. The new zone map is below.
