"The fact is that the average man's love of liberty is nine-tenths imaginary, exactly like his love of sense, justice and truth. Liberty is not a thing for the great masses of men. It is the exclusive possession of a small and disreputable minority, like knowledge, courage and honor. It takes a special sort of man to understand and enjoy liberty – and he is usually an outlaw in democratic societies." –- H.L. Mencken, Baltimore Evening Sun, Feb. 12, 1923

I've seen em built out of lawn mower mufflers too...where there's a will there's a way.
