ohio??

Its a very good movie and as I said in another post I lived in NYC for a few years in the late 70's and this movie is dead on accurate, but the question have is unless they came from a small town in ohio why were so naive about a big city???Ohio has many big cities that are full of crime and bad stuff happening and Im assuming hes been on many business trips around the country so you think he would be wise to what a big city is all about.
