Dean and 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.
