A few years ago I part of the 'transport corps' to my youngest nephew's 10th or 11th birthday party (can't remember which). It was a Scalextric party held in a barn with some chap who did it almost professionally. I couldn't believe it; he had them split into teams, drawing racing colours, making flags, charting lap times, working out pit strategy when they weren't racing, telling jokes and giving them a whale of a time. Lashings of pop and slices of pizza, trophy prizes and laps of honour all ended up with tired, smiling, happy faces. The chap was a complete natural, a magician... and certainly earned his fee that night.
