Camped just S of Oak Flat as a large group of Boulderers had occupied the campground. A good group. Hiked S on roads and jeep trails to Hackberry Canyon exploring and enjoying the breezes. A fidgety blacktail rattler let us know this was his territory. Checked out many hoodoos and flowers. Watched a jeep caravan attack the ridge we just hiked with steps and boulders 3' high. Made a small loop to the W on other roads and returned to our camp via original route.
