Looking at the J.Doe site reminds me that last summer I met
an art teacher whose art club participated in the pig event.
They raised enough money to buy a pig. They put covered it
in buttons (even made the local news), and then raised
enough money to buy the pig when it was finished, and have
it displayed in their school.
Good idea for an art club if you happen to be in one of
these 'event' cities.
