The world goes around

I have been inquisitive since an early age. It amazes (and delights) me to go to a shipping or receiving facility and seeing how things are made. Driving a truck really does show you economics at work. For instance, going to a plastics facility and having them load the entire 53' trailer in one motion. The plastice bottles (for Coke, Pepsi,
beer, etc) are formed onto pallets and the pallets are lined up inside a raised area on the floor so that the forklift only has to push the entire 53' line of stuff onto the trailer. Aluminum cans are done the same way.
