I completely forgot the Great Circle requirement -- it was 2:00 a.m.
Although the routing from CMH is closer to a GC route, CMH is significantly farther from Findlay, so I don't know which to prefer. I think that DTW is actually a wee bit closer. OTOH, I recently flew from ROC which is farther from me than either of those is from Findlay. And if CMH is close enough, FWA and DAY might also be.
