I've had an odd idea on this subject: when a state is split between boards, how about we try to make an "official" boundary that follows DOT district boundaries? I should hope the reason is obvious here. So for Ohio, maybe we could have 1, 2, 3, 4, 6, 7, 12 in Midwest / Great Lakes, while 5, 8, 9, 10, 11 are in Ohio Valley, for example. (Or maybe throw 5 and 11 on M/GL, or throw 6 and 7 in OV, but in any case pick a plan and try to make it official.)
