I am Aragon and own every Mediterranean coastal province from Macedonia to Ifni except Tangiers, Edirne, Thrace and Tunis. In order to have a land route to these provinces so they are no longer "overseas" do I have to have the route all the way to Spain or will a route to any European province do? In other words do I have to annex southern France, northern Italy and the Balkan coast as well as a route through southern Russia or can I just grab the southern Russia portion giving me a land route to my Greek provinces? I assume taking Edirne and Thrace would not count as a "land route". The reason I am asking this is that all of Anatolia up to and including Mus have a positive tax value as well as the N. African province up to Gafse. this implies the distance calculation for Anatolia is coming from the Greek provinces not my home Spanish provinces as I have no land link to the Greek provinces but they are European so I get tax value for them.
