Australia's obsession with Big Things didn't start with Coffs Harbour's Big Banana, Woombye's Big Pineapple or Robertson's Big Potato. It started here in Adelaide with a giant Scotsman that still stands sentinel over one of the city's busiest intersections. Greg caught up with the man who kick-started that obsession, Adelaide artist Paul Kelly. Thanks this week to Paul and Pam Kelly, Ian Backler and Dr Amy Clarke.
