I would make the case that Oklahoma could become the new Vegas. It’s more centrally located in the country. A lot of the land is run by the Indians, so you could see a big expansion over what they already have there.
Tunica, MS tried that and it worked for a little while, till move gambling options opened up. Now you can gamble almost anywhere and the casinos trying to get every penny out of you before you even gamble ain’t helping.
