I have been to a couple of the missing states when I was in my teens, but if I don’t remember it, it does not count I guess.
Fun story about South Carolina. I was in Charlotte for work, and was struggling to find decent places that were not chains to eat dinner at. I was determined to go to South Carolina “just because” so one night I drove down. As soon as I crossed the border, there was a. “Locally sourced, organic, home made” restaurant.
So solid win in South Carolina.
