Trip to Buttermilk Springs
It's not far. Total distance is 6.5 miles. Head toward Caddo Gap, go just to the other side and look for Buttermilk Springs Rd which takes off to the right. Follow the road for about 2.8 miles and look on the right for a PVC pipe coming out of the side of the hill. The spring is just above it.
