I swear it was random; no money changed hands, no favours were offered.  Leanne won fair and square.  We didn't have some dude in a suit auditing the process - I just had my wife pick some numbers out of thin air without telling her why.  All those who picked up a BroCard at the show were eligible but there could be only one winner.

Anyway Leanne was stoked.  Her bike locker had been broken into recently so she deserved the good karma.
