Washington would like a word with you regarding active volcanos.
Oh oh!
Isn’t Michigan the only state with a 10¢ bottle/can refund?
Michigan not only has the most fresh-water shoreline in the States, but also the world.
Arkansas is the home of the hot springs baths in Hot Springs AR. Some of the country’s most infamous gangsters (Al Capone, Pretty Boy Floyd etc.) in the 1930’s soaked in the natural spring waters and gambled in the city’s night spots.
Damn, Texas is doubly stupid for our supercollider falling through, then.
Okay, since no Louisianans have showed up yet and even though I’ve only spent a few hours within its borders, I’ll add two that’ve been burning a hole for me.
Louisiana is the only state (in the entire world AFAIK) to have parishes rather than counties.
Louisiana is the only state to have had an Indian governor.
hells yeah we are!!
Heard that one back in the seventies in the northeast. A bastardization of bogus, iirc.
In South Carolina, you can use a nice hot piece of apple pie, if you like. 
Not so. Also in Western Pennsylvania.
Bubblers abound in Chicago as well.
Yeah, but it ain’t as cool - nor as accurate - as the Michigan mitt. 
Regarding roadways, there is also what we call a ‘Michigan turn’. Basically, at a busy intersection, you have to turn right if you want to turn left.
‘Bogue’ we used to say back in the 70’s (yes, in Michigan). I believe it is similar to ‘don’t bogart that joint’. It sounded stoopid even then.
And let us not forget Vernors, Strohs, & Faygo (not exclusive to MI, but originating here).
I don’t know of any other place like that, and that is way cool.
But in MA, on the Cape and islands, we use “up” and “down”, as in upcape or downisland. It has nothing to do with latitude and everything to do with longitude.
There’s an old joke about tourists on Martha’s Vineyard. “Excuse me, can you tell me how to get to Upis Land?”
Speaking of which, MA is the home to the oldest still-operating carousel in the country. Or maybe Rhode Island is. Both were built in 1876, and both are called The Flying Horses.
Rhode Island is the only state to have had controversy over the official state beverage. FWIW, it was coffee milk vs. Del’s Lemonade and coffee milk won, if you can believe it.
Pre-schoolers across the country play the game
duck, duck, goose!
Except for the preschoolers in Minnesota.
They play duck, duck, grey duck.
If you’re going east on route 4, between Mendon and Killington, and you want to turn left (north0 onto Winterberry Road, you’ve got to use the “left and u-turn” lane.
Vermont has a cemetery which limits your choice of material for your headstone to one: Barre Gray granite.
California doesn’t have a functioning Governor’s mansion, BTW. It’s a museum now.
Hell, we don’t even have a functioning governor! 
We’ve got Jughandles all over Michigan.
We also have what I’ve always known as “Michigan Lefts” (or “flipping a bitch”). There’s a median between both directions of traffic. In order to make a left had turn from and intersection, you first have to make a right turn, then enter the U-Turn lane and continue on your way. Anyone else have these?
I always thought it was funny that we called them Michigan lefts, since we’re in Michigan. It seems like the kind of name another state would use.
We had some co-workers come up from my work’s home office in Florida. They had a GPS and I heard a few times, “It’s telling me to turn left but shows I should turn right! What the hell is this?!”
Euchre’s pretty common in Indiana too; just about everyone in my (Hoosier) family plays it.
Arizona…hmmm:
A state where it’s common to see rivers with no water in them. Don’t know if NM is the same.
The only state with a Grand Canyon. Oh, sure, you may have a canyon in your state, but ours is grand.
The westernmost battle of the Civil War occurred between Phoenix and Tucson.
