White Rock Mountain... 10 miles NNE; 14.2 miles via gravel, paved, smooth gravel, rough gravel, washboard gravel, then good gravel again as you go steep and steeper, so 45 min drive from my bluffs. Colors spectacular in the autumn. Do the Rim Trail.
Me and Ranger Hank a few oreos ago at low water crossing below the swimmin' hole. :-) Yep, seen a few ATVs and dune buggies stop or stall half way across.
