I wonder if some of the oddities generated by the "neato" and "fdp" engines (e.g. SC behaving like a peninsula) would be addressed by also modeling the borders with the oceans (i.e. the coasts) and with other countries -- just like he modeled the borders between states (e.g. the ocean would "push back" on SC).
