Johnny make up the grounds crew. They do a little bit of everything,
from maintaining the walkways for the public, to planting trees, mowing, and
many other "as needed" assignments. In these two pictures they are
stabilizing the ground around a steel structure that houses the fiber
optic connection from the arms of the array to the control building.
They often use large pieces of machinery and heavy equipment but are
equally talented in the wielding of shovels and brooms.
