I live at exit 38. A few exits before Kingsland. They are building a brand new Buc ees at exit 42. Just broke ground Monday. Should be ready for you next year!
So my next question is this. If he buys a bucket I'm assuming it counts 6 towards his 15? Will they be open or does he have to open? It will be cheaper to buy the bucket and bring back to the room whatever he doesn't drink but that wont work if they open them for you.
