Oklahoma Camping

Thanks for all the tips so far. Yes, the Chickasaw National Rec Area is where we'll spend a lot of time. I did see the Wichita Mtn refuge, maybe we'll go there instead of Red Rock Canyon. Looking forward to the trip!
I received a travel kit from the Oklahoma tourism office, and browsing through it I found so many choices. As you know, you have to whittle it down, just not enough vacation time.
