Casey & 
Casey & Skatie.
Casey[]
The best of the best.
In the making for a long time.
But doing it for the passion of it.
All earthy possessions fit into one suitcase.
Except the most important one.
Which he is tending to like nothing else.
Looking for The Wave.
But understanding it is about the journey, not the destination.
Wearing a lucky talisman.
And often needing it.
Dreaming of winning The Competition.
But really wanting to settle down.
Casey & Skatie[]
Katie 'Skatie' Boulton.
Avid roller skater.
Outgoing beach comber.
Casey 'Hang Ten' Schultz.
Surfer legend.
Beach is his home.
They fall in love.
Settle into Beaumont Hall, with the calmest beach on earth.
Waiting for a legendary wave that never comes.
Bored Casey combines surfboard and skates.
Surfers come, looking for the champion and his wave.
And leave with a skateboard. Casey's Skateboards is born.
