My father worked for Caterpillar. There is a plant where I live, and yesterday we all took a tour, in honor of the 50th anniversary of the plant, which was truly awe-inspiring. Some of these trucks weigh 360,000 pounds! Engineering genius. And not just the trucks, the buildings themselves. The details involved in designing the trucks, the specs, and such, are equaled by the design of the assembly process itself. Blows the mind.
But the best part was the CAT Chopper. It's gold and looks so cool. It travels around the country to different exhibits. Awesome, dude!
It's too bad they don't make these for the public. I'd certainly like to have one.
