'Concrete oil tank, probably only one built. The remants of two tanks (concrete) are visible from the top of Petroleum Road. These tanks, and the one in this photo, appear to be water tanks. Water was needed for the steam engines. (Note the water in your tank) Oil tanks were either wood, or metal. The metal tanks could be moved from one site to another. When the gushers first came in there was labor unrest because the coopers were making more money than the oil workers-barrels could not be made fast enough to meet the demand.'--Mike Naylor, 03/2006
