Ok after some thought colorado/nebraska/arkansas/missouri would all be friends-
The first three all share the same vibe.
I wanna think the three all got high together at least once and just for hours sat and talked about whatever came to their heads first.
Missouri would either smoke with them and join in or he would sit out and just w h e e z e at what they are saying.

Idk much about state rivals but would they actually get along or am i just being hopefull-
