Australia Sand Dune Motorcycles

In australia in august with spence.  Have futuristic white panel motorcycle (crotch rocket) that turns on when you screw a bottle of water into it.  Go fast down some sand dunes and a little into the water on it.  See some girls and want to talk to them so I go up to them with my motorcycle.  I ask them for the time in an australian accent, which gets progressively worse.  They are beautiful and seem friendly.  I ask them what they do at school and they say they are on winter vacation.
