'Our kinda town' has a North Ave. that was (if I remember kerrecktly), at the time of "The Fire", the northern border of the city (which became immediately meaningless when the land stood scorched), and 'til the turn of the 20th century, Western Ave was the western border. There is no east Chicago unless you mean the town East Chicago which isn't actually® east of Chicago and not even in Illinois... which explains why the neighborhood 'South Chicago' is what *we call "The East Side".

edit: beware all you geographical nitpickers, I'm a northsider.
