Tons of dispersed camping

Both areas, Castle rock, Gulch, and mushroom gulch have forest roads with multiple disperse, camping spots off the road in both open and secluded areas. Including areas where multiple vehicles can park and camp in the same central location. Roads continue for miles and miles with many camp spots. Some roads are well maintained while others are rockier and more rugged.
