:Hello. 
 :The Navbox template requires that the "name" parameter be set to the new template's name in article space.  In short, it should have been "Georgia (U.S. state) hiking trails" instead of "Georgia hiking trails".  That was why there was an issue.  The "name" parameter has no effect on the template's appearence if the "title" parameter is set. 
 :{{subst:PAGENAME}} is a quick and easy way to set the name parameter correctly.
