Minnesotans avoid "Friday the 13th" like the plague. Iowans really love to rely on lucky pennies. The history of this superstition indicates pennies are not actually lucky unless they are facing right-side up on the ground.  Basically, don't pick up the penny if it is showing its tail or if the penny isn't shiny...
