Our Green Tortoise South Park Loop Trip, Sept., 1998. Where: White Sands Park. Open spaciousness, no people. Click on photos to see full screen view. A fine spot for the road to end. Florian leads the sunset choir atop a White Sands Knoll. The desert brings out all sorts of urges. Hygiene check. A passenger zooms down the sand on a make-shift cardboard sled. Florian and other friends.
