There's a riding park just up the road from Tenkiller. It's called "Gruber ORV." Very rocky and usually quite a few people there. Probably half the trails are closed during hunting season (they fence the hunting part off). But, the place is better than nothing. I've ridden there several times. But, if you're close to Tenkiller, then you aren't too far from Mill Creek/White Rock just outside of Fayetteville, Ar. YOU MUST GO THERE! Excellent place to ride, several miles of trails. Well marked, etc. You've got a couple tracks in your area. Dora, OK (Ascot) and another one just south of Muskogee, the name escapes me. Not to mention a bunch around the Tulsa area. You're in a good spot! (Didn't mention the sand dunes at Little Sahara in Waynoka -- probably 3 hours or so from Tulsa and also a MUST at least once.
