great photo of a Mack plowing streets about a hundred years ago. Look at those back wheels

from the 100 year old photos website, Shorpy.com

Steam shovel and an old Mack

A generation of hard working men with no comforts. No air conditioning, stereo radios, pnuemtic tires (those are solid rubbber) or suspension. Long hard slow lousy days at work, with a hat. Every guy had to wear a hat.
