My Dad tells stories of his grandfather, a lifelong train engineer, chastising him for crossing tracks without looking both ways before crossing. Protective gates or not. He would say in his southern drawl "You wanna die Son!!" Since then, I have always stopped and looked. I don't trust mechanical things like that to protect me. Same goes for gun safeties.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.
- Samuel Adams
