Almost had me "which Cherokee casino?"
We have at least six now, and some are almost within a stone's through of another nation's casino, because the Cherokee Nation has pushed some locations out to their boundaries. In Tulsa you can choose between Osage Nation and Cherokee Nation casinos with a short drive on the freeway.
Most either have RV parks or have attracted a KOA or something like it nearby.
If you want casino gambling with low overhead (much cheaper to visit than Vegas) come out to Oklahoma. Thirty tribes now running 90+ casinos all around the state, some of them pushing into Kansas, which also allows tribal gaming but has fewer tribal lands.
Michigan has also been getting into the business in a big way, a big tribal casino just outside Battle Creek, in addition to those that have been in the northern resort areas for many years, long before Oklahoma opened up to gaming beyond Bingo.
