At one point I was expanding this island with plans to do a more political mini campaign on it, if I remember right. Here is a more detailed scale map of the island.
I also had some political boundaries and names in overhead pen on the plastic over the main map. I took a scan of them for record before wiping them off to scan the clean map in the other night. Amazingly, blue Vis-a-Vis pen wipes off clean after decades.
