Solid map. I disagree about the advantage to players starting in the north. Nevertheless, the bonuses are a bit less generous in the south. I suggest equalizing bonuses by number of territories in them. In other words, if a you're going to give 4 bonus armies for holding one area of 5 territories (e.g., Prime Hook), then give 4 armies for all 5-territory bonus regions (e.g., Delmar, Assawoman, etc.)
Also, there is a broken link between Fleming and Prior Park in north central Delaware.
