A thought about cars and nature

From the late great writer Ed Abbey: "We've got to close the parks to private cars if we want to keep them as parks. The parks are for people, not machines. Let the machines find their own parks."
Hah. One could easily apply this thought to any number of places/sites/neighborhoods/municipalities/counties/states and make, in the process, real contributions to the betterment of our collective quality of life.
