This probably drove my parents nuts, haha... I remember being on trips telling my parents they couldn't go by those "No Passing Zone" signs by the highway. Also, stop signs made no sense... How long do you stop? How do you know when to go again? No wonder I got D's in driver's ed.
Also it was cool as hell the day I realized that some of the streets go in numerical order in my town from north to south.
