One is the moving enterprise of a friend in Philadelphia whom I love and deeply admire. One of his vans happens to be of that cadmium yellow hue I tend to associate with my personal work ethic: honesty, efficiency, simplicity, and resourcefulness. These happen to be precisely what my friend embodies.
The other is what some taxis looked like after the twin towers rained down on lower Manhattan. It's easy to maintain the qualities mentioned above, until it is made apparent that people of power choose not to play by the same rules. Even worse is when something seriously fishy is going on and the rules start not even making any sense anymore.
