Grouping states in three

[President Punxsutawney Phil]

Excluding Alaska and Hawaii, how would you group states in trios?
The lower 48 can be divided into 16 3-state groupings.

Decided to try the first time to do something out of the box.

Far from perfect, of course, but about the best I could manage at a first attempt.

The eastern part of your map is pretty much identical to mine!

It is quite similar yeah.
I quite like the Great Lakes grouping of MWM and IIO. It has a great look to it on the map.

Can anyone think of a way to make WA-OR-ID work?

I tried and doing so messed it up . I can’t tell you how much i hated grouping OR and WA with CA

I think I just thought of a way to do it. Stay tuned.

[President Punxsutawney Phil]

Not a fan of UT being with CA but I got AZ-NM-TX in return so I'm not unhappy.

This is quite well-done, wow. I had something kind of like that on the drawing board before scrapping it. It does seem that CA-NV-AZ is generally the best way to handle CA, if you can't reach the PNW.

The idea here was initially AL+GA+FL, before morphing into "let's cross rivers" kinda.
