Thanks Max, a great afternoon was had by all. Thanks also to Lana (Mrs GAP) for offering to come down with me and cook the BBQ. The machine for the Rusty Balls comp was picked by Lana putting her hand into Max`s ball bag, sorry - into Max`s bag of balls and selecting a ball at random that was marked Safecracker, I reckon all 10 balls were marked the same   
Thanks to Gibbo as well for saving the Rusty Balls award going home with it`s maker.
