The American Indian sat beneath a Joshua Tree. Removing his safety helmet, he turned his head to the right and contemplated the convoy. The blue and red escort van, barely visible through the surging dust, was in front. Cars, trucks and RVs followed but the convoy crawled because of the dust and stones. The wide, unpaved road sloped downward through a cactus forest, and the dust erupted under a cloudless blue sky. About quarter mile from where the vanguard had reached the road began climbing again in a long curve. In the flat before the incline, two bulldozers were pushing dirt from the middle of the road to embankments along the edges. A dump truck was inching up the slope. Two were coming down. They'd been going all day, pushing, loading and hauling dirt.
