I use the site you posted as well
Yes I did find out what I needed to know, thanks for asking. Surprising that area of Oklahoma is very un-plain like, the Ozarks from Arkansas spill over into that area. Its very pretty but the trails that we have ridden are very
rocky. I hate riding where I have to worry about every foot fall.
Just FYI for your web site. I always try to find out if shoes are recommended or necessary. Information that I think is very important but so many leave out on trail descriptions.
