Which US states have cultural ties with more than one region?

Maryland, Delaware, DC, and Virginia are all deeply southern states, but to varying degrees are closely tied to the adjacent northern metros and are part of the BosWash corridor.

Florida is Southern too, but there are certain Northeastern aspects to the Miami area, and some cultural influence from the Midwest in Southwest Florida.

Colorado, Wyoming, and Montana are Western states but have certain midwestern aspects as much of them are extensions of Western Kansas, the Dakotas, etc.

Hawai'i doesn't fit well into any U.S. regions--it's properly a part of Polynesia culturally, or just its own thing--but there's a lot East Asian influence, as well as obviously some similarities to the Western U.S.

There are obviously more examples but these feel the most salient.

West Virginia (Northeast, Southeast, Midwest) and Texas (Southeast, Midwest, West) are the only "tri-regional" states. 

I'd throw Oklahoma in there as well with the same 3 as Texas.

I think El Paso makes it a bit easier to classify certain parts of Texas as Western--there really isn't anywhere as culturally Western in Oklahoma.
