I've got a crooked elbow and I generally say my prayers with one leg on a brass rail. - Edward Abbey

There is this to be said for walking: it is the one method of human locomotion by which a man or woman proceeds erect, upright, proud and independent, not squatting on the haunches like a frog.
Little boys love machines. Grown-up mean and women like to walk.

Devoted though we must be to the conservation cause, I do not believe that any of us should give it all of our time or effort or heart. Give what you can, but do not burn yourselves out — or break your hearts. Let us save at least half of our lives for the enjoyment of this wonderful world which still exists. Leave your dens, abandon your cars and walk out into the great mountains, the deserts, the forests, the seashores. Those treasures still belong to all of us. Enjoy them to the full, stretch your legs, expand your lungs, enliven your hearts — and we will outlive the greedy swine who want to destroy it all in the name of what they call GROWTH.
God bless America — let's save some of it.
Long live the weeds and the wilderness yet!

Let's have some precision in language here: terrorism means deadly violence — for a political and/or economical purpose — carried out against people and other living things, and is usually conducted by governments against their own citizens (as at Kent State, or in Vietnam, or in Poland, or in most of Latin America right now), or by corporate entities such as J. Paul Getty, Exxon, Mobil Oil, etc etc., against the land and all creatures that depend upon the land for life and livelihood. A bulldozer ripping up a hillside to strip mine for coal is committing terrorism; the damnation of a flowing river followed by the drowning of Cherokee graves, of forest and farmland, is an act of terrorism.
Sabotage, on the other hand, means the use of force against inanimate property, such as machinery, which is being used (e.g.) to deprive human beings of their rightful work (as in the case of Ned Ludd and his mates); sabotage (le sabot dropped in a spinning jenny) — for whatever purpose — has never meant and has never implied the use of violence against living creatures.
