BDR or Back-country Discovery Route is pretty much an organization in it's own right. Take the two letter Postal designation for any state and tack it in front of BDR call up the internet and see if these folks have put together a Route. LOL, there's only a few states with a BDR that I'm sure of, and those are all west of the Mississippi. In all likelihood the list is being worked on. The routes get modified every Spring, got to keep an eye out for the changes.
