Location: Billy Johnson Mountain Lakes Preserve into Coventry Farm Park, head north east and follow signage saying devils cave, I believe you’d be following the yellow trail again into Coventry Farm Park (on Maps app for Iphone) north to toward Stuart RD.
Beautiful trail with some amazing boulders sat amongst the quiet forest, some larger boulders are really tall and have good drops mostly around but also in between if I remember correctly, keep an Eye on Children and Dogs if your going to Venture onto the Larger Boulders.
Truthfully, it may actually just be a hardened piece of Tree Sap
here comes the stiltgrass!!
