Took the hill trail for the first time this morning and really enjoyed the experience. Since I had time to kill, I started wandering trails to see where they may lead. Ended up crossing the power line into the preserve and coming out at the trail head to Jester Mountain off Gutherie and Aralia. I was actually happy to see the City is providing limited access to the Balcones Preserve lands. Many, many warblers as you ascend to the higher areas. Saw a birder, another lone hiker, two mountain bikers, photographer, and two families. Great day to be out!
