Man walks up grassy hill, grassy fields in distance. The grass blades ripple, and a nearby tree’s branches sway, in a rough wind. Cars on busy highway. Shot of trees with mountains in distance. Shot of cacti and shrubs in desert. Harvesting machinery (wheat combine) collects wheat in farm field. Cars on highway. Some sort of power plant (possibly thermal/steam). Shot of dam, two trains passing each other, then oil well and oil pumper. Moving shot of well-maintained houses in nice neighborhood, then car parked in found of house. Shots of large machinery moving freshly downed tree trunk destined to become lumber, then pile of tree trunks on flatbed. Shot of ship bow, then plane speeding along and talking off runway. Close ups on turning wheels on train, a turning gear in a pocket watch, turning wheels on a machine—all require lubricants.
