Syd -> Mildura is 10 hrs Mildura -> Radelaide is 5hrs.
Can break it up a little with lunch and stuff, won't be too much of a slog. Need walkie talkies for some in-car trivia.
And the return trip I'll sort out with Matt, and post up if anyone else wants to join. I sure as shit ain't driving 15 hours flat after the nats, I'll be dead.
