We'd do the rock stuff if it were dry (to keep the dust down); I'm assuming it's moist so we can do a higher pace in the open areas without the mosquito-abatement effects.
Just after the fork; straight ahead, a few hundred feet on your right.
I have to leave no later than ~noon as there's a car my wife wants to see. I expect one good loop will get us back to the trucks - er, econo boxes - by then. (J/K Holeshot: we test drove one today.)
