Greetings EB fans. I've got a question about the provincial boundaries, especially in Iberia (I'm playing Lusotanni, natch). Specifically, where or what are they? Blue lines are for rivers, right, and brown is for roads, so what color (or markings) denote provincial borders? After all, one doesn't want to build an expensive mine to develop a precious metal vein that isn't even in the province. Thanks for your kind attention.
