Combined the Schoolhouse Loop with Overland Loop and Grindstone Quarry Trail (out and back) for a 6.2 mile hike. On this date the trail was dry and free of any snow or ice. A nice trail through the pines and rolling terrain. The views are a little better on the Quarry Trail compared to the loops. They just added some of these trails, so the AT map is not up to date. See map at the trailhead.
Short and flat new loop added on at Heil Ranch area that connects to Overland loop. Pretty views as you go for a sec along the water then up and around through the open pastures near the forest. Everything this time of year (May/June) is soooo green and lush.
