You used to be able to get it here in West Virginia, but now you can only get the 151 proof (watered down) bottles.
The reason that it is so hard to find is that it's, potentially, deadly. It is pure alcohol.
Many people have been hospitalized from alcohol poisoning, due to drinking Everclear.
I used to like making jello shots from Everclear (the 190 proof).
I had to take a girl to the hospital one night, after she saw the pan full of jello shots, and decided that it would be a good idea to suck up half of the tray at one go.
In less than five seconds - she had consumed about a half a liter of this stuff. If you have ever tasted Everclear you would know that it tastes like fire and leaves a burning pit in your stomach.
"Wow!" I said "That was incredibly stupid."
To which she replied: " I don't feel so good", and proceeded to lye down in the floor.
If I had not taken her to get her stomach pumped, she would have died right there on my floor.
