There is also Clayton, OK near there as well. My club did it last fall, but I missed it because of a business trip. From what I hear it's everything from scenic runs through the country-side to trails you only try in a rock buggy.

Looking at the maps, Clayton, Broken Bow and Smithville are all within 60-90 minutes of each other. It could be we try one place and if we don't like it go somewhere else.
