Helgelandsmoen
It’s another map. This one is from Helgelandsmoen in Norway. It’s a challenging peninsula. There are only 4 customs due to the mountainous borders- one large and one small for each border type. You will likely need to use ships if you want to do any serious exporting of resources. Another challenge is the hilly terrain around the borders that will require you to space your starting town a bit further from the border. Are you up to the task?
