A version of softball that originated in Chicago, IL.
It is played just like regular softball with a few exceptions:
The ball is considerably larger and a bit softer than a normal softball.
The ball is stitched together much differently than a normal softball.
Since the ball is so large, gloves are not permitted (the ball is so big, it would never fit in a glove anyway) and the ball must be caught with your bare hands. According to a friend from Chicago (who introduced me to the game), this is because the people who invented the game could not afford to buy gloves.
