"It's like a cruise!"

 To get to South Island you have to cross the Cook Strait.  It's about a 3 hour journey with some pretty amazing scenery along the way.  Courtney was surprised at the size of the ferry and remarked "ooh, it's like a cruise!"  I think she was expecting a wooden raft or something.

 

Sheep making the crossing to South Island...and probably someone's plate.
