Do you throw litter from your car?

[barefoot serpent]

Abbey confounded environmentalist proprieties about "littering" by tossing his beer cans out the window onto roads he hated, such as the new paved road to the Bullfrog Marina at the Glen Canyon National Recreational Area. As he explained in "The Second Rape of the West," "Of course I litter the public highway. Every chance I get. After all, it's not the beer cans that are ugly; it's the highway that is ugly."

from Edward Abbey: A Life, by James M. Cahalan

also another way to look at it is that roads will become the mines for future generations.
