Good work! Kinda annoying they want Fairfield when Franklin + Delware + Morrow is like exactly 2 districts.
I think this is an instance where COI > minimizing county splits. Even though Morrow is technically within the Columbus MSA it isn't really part of the Columbus core. Fairfield actually has some parts of Columbus proper within it as well as several bordering suburban cities.
However, I do think it is odd to insist on including a part of Fairfield specifically. There are portions of Licking and Union that would make much more sense from a compactness point of view.
