I could be wrong but is Mexico, New Austin, West Eli etc. They're only a few areas aren't they? So it's not like the HOLE OF AMERICA or the HOLE OF MEXICO.
I think it's correct that's why John's house is in Blackwater (away from other counties his been in as the storyline says) and then all a sudden Williamson & Dutch slowly made their way's over to that area of America and etc?
Or is that wrong? ON TOPIC - if it's correct then the map suits me fine, if not and they based it on the HOLE of the USA & MEXICO then it's a little strange and small yes.
