Hawaii: Maui and Kalawao (although I'd prefer to make a Molokai County including Molokai and Lanai)
Lanai probably has more in common with Maui than Molokai. Its economy is tourist-based, with one or two very upscale resorts for the mega-rich. It’s 97% owned by Larry Ellison, the chairman of Oracle. In contrast, very few non-Hawaiian tourists find their way to Molokai, except perhaps to visit the leper colony in Kalawao County. It’s rural, agricultural and poor.
I don’t think combining the two disparate islands into the same county without Maui is a good fit.
