A peninsula is 3 sided, a county on the other hand would have 4 or more sides (depending on the shape of the county) unless of course it was shaped like a triangle and then it would only have 3 sides like a peninsula but not really like a peninsula because a peninsula is not really shaped like a triangle, yet if a peninsula has broken off and fallen into the sea then it would have four sides and thus will have become an island unless eventually the sand has filled in the space between the island and the land, then it would be reconsidered and rezoned as a peninsula except when in the case where the body of land in which it has joined is not really phallic shaped but more of a rounded off globual mass of land, then and only then could it be considered a 2-5 sided county.
