I am not sure why, but I seem to dodge alot more spit on the sidewalk in Chicago than I did in DC. Do people hock it up more in the midwest, I wonder?
Laws, or at least good manners, date back to early last century. Here is an interesting story about a doctor, so worried about tuberculosis patients expectorating in public places, that he had the words "Don't Spit On The Sidewalk" engraved in bricks that were placed in sidewalks in a town in Kansas.
There is a law on the books in Chicago that prohibits spitting. It is sandwiched between the law that forbids eating in a place that is on fire and the law that states it is illegal to give a dog whiskey. Some other interesting Chicago laws are:
• Kites may not be flown within the city limits.
• It is illegal to fish in pajamas.
• People who are diseased, maimed, mutilated, or "otherwise an unsightly or disgusting object" are banned from going out in public.
• It is illegal for anyone to give lighted cigars to dogs, cats, and other domesticated animal kept as pets.
• It is illegal to give a dog whiskey.
• It is legal to protest naked in front of city hall as long as you are under seventeen years of age and have legal permits.
• It is unlawful to change clothes in an automobile with the curtains drawn, except in case of fire.
• The English language is not to be spoken.
• You may be arrested for vagrancy if you do not have at least one dollar bill on your person.
• You may be convicted of a Class 4 felony offense, punishable by up to three years in state prison, for the crime of "eavesdropping" on your own conversation.
• You must contact the police before entering the city in an automobile.
And in Champaign, IL, one may not pee in his neighbor's mouth (does anyone else see the irony in this?)
