Membership Cost = $00.00
Who can be a member? = Membership is very, very exclusive.  Only those who lives Nort' of anyone else can join.  So of course someone in Wisconsin is Nort' of folk in Florida, and folk in Florida are Nort' of those in Cuba.  And those in Cuba are Nort' of those in Brazil, and they are Nort' of those in Antarctica.  Folk in Antarctica are only Nort' of someone if there is a penguin sitting on the true South Pole and that poor penguin would not be allowed to be a SKUNK. 
SKUNK rules:  Be civil, be courageous and don't raise a stink.
