Adjacency List of States of the United States (US)

Some simple data is surprisingly hard to find.  Case in point: for some mapping projects, I wanted an adjacency list of the US states.  I couldn’t find one easily, so I made one.   Spread it far and wide!  This should be a pretty easy to digest form.  Figure out what states are next to each other (neighbors) with ease!

Potential gotchas:

1. I say the four corners (UT,CO,NM,AZ) all touch. If you don’t like it, take them out.
2. DC is a state here, but Guam, USVI and others aren’t.
3. It’ll be a cold day in hell before I recognize Missouri.
