The human mind is the world's deadliest weapon. In the hands of a trained individual, even a ball point pen is a weapon. The knives that ride in my pockets, and on my belt are tools. The folding E-tool behind the seat of my pick up is just that, a tool. Once need arises, I am the weapon. Whatever I use is still the tool. If things have digressed to where I need to use a tool as a weapon, I have already failed by letting the situation digress to that point.
What it all boils down to is this. Every tool is a weapon, and every weapon is a tool. Plain and simple.
If I have to explain why I ride, you wouldn't understand. Explaining sex to an alien would be easier than explaining the feeling, one that boils all that is going on in your life down to what really matters each time you are in The Wind. All I can say is, Life is not Life without it.
