Casinos hold less than zero interest to me. I don't begrudge the native american tribes for having them, but I have a natural dis-inclination toward games of any type. Playing golf is as close as I get to any game. "...mile for mile, ... the most diverse terrain"? I don't know what the caveat is for, but I don't think so. It's not like Oklahoma can compete against Colorado, Montana, or Arizona. You don't see millions of people planning their vacations to Oklahoma. Sure, I'd like to ride there but Oklahoma is toward the bottom of a long list. I've been to the National Cowboy and Western Heritage Museum in OKC. Great place. Possibly the best of its class in the world. Its the site of my first "museum ephiphany" of which I've had several since. I spent fourteen years living in Arizona... hiking, camping, and exploring it and the surrounding states. Yet it was only after spending 2-3 hours at the museum in OKC that I was hit with the epiphany that The American West as we preach it is a myth. John Wayne, Manifest Destiny, cowboys & indians, self-reliance & individualism - it's all hogwash. But that's a sermon for another Sunday. If you haven't been to the NC&WHM in OKC - get yourself down there. Enjoy the art and artifacts of one of the few things that make America unique in the world. And if you can't get down there, spend a half day at the Eiteljorg Museum in Indianapolis. It's a smaller version of NC&WHM with credible content in its own right. In the first room on the right is a multi-panel landscape mural of the Grand Canyon. If you have never had a "museum epiphany", sit down on the bench in front of that mural of the Grand Canyon and stare at it until you see its 3D content. You may not see it at first, but once you do its impossible to see it as a 2D painting. I've been to the Grand Canyon multiple times but in some ways that mural is better than the real thing.
