David Casarez has a ton of experience in web development, a relatively in-demand field. He graduated from Texas A&M University. He is articulate and intelligent enough to piece together a resume that lists all of his skills and past work history.
He was also out of a job, and fell on hard times. So hard that he became homeless and resorted to sleeping in parks in the Mountain View, California area.
Rather than flipping the system "the bird," David got dressed, made a sign, and went on the highway to ask people for help.
But, his idea of "help" was different than other roadside panhandlers you often see during your commute.
