Do you get nervous?

Something that is always on my mind. My only driveable project is my 51 Fargo at the moment. Its a beater by some standards but i put a lot of work into it. Breakdowns are iminent as well as some careless driver running into me or cutting me off. Plans are long road trips and a couple hotel stays. Whats going to happen to it parked all alone at night in a strange town?
