Cannery Row by John Steinbeck:
The next owner took off the front of the cab and the windshield. He used it to haul squids and he liked a fresh breeze to blow in his face. His name was Francis Almones and he had a sad life, for he always made just a fraction less than he needed to live. His father had left him a little money but year by year and month by month, no matter how hard Francis worked or how careful he was, his money grew less until he just dried up and blew away.
