Our Green Tortoise South Park Loop Trip, Sept., 1998. Where: La Kiva Campground. An authentic (!!) Texan Bar that allowed us use of their washing machine. The Green Tortoise East-West migration trip crossed paths with us there, and it was fun for everyone. This was our base camp while we explored the Big Bend Park area.
