From this day forward The Amateur Putt-Putt Association and Tour (APPAT) shall be known as the Amateur Putting Association and Tour. (APAT).
I reckon a putt-off could be a good little challenge, and won"t take much longer than 2 hours (absolute max)...
All ruck up at a crazy/adventure golf centre, divide into groups of 4, and play 18 holes. The lowest score scoops the trophy, and perhaps a cash prize?...
Will add to OP tomorrow, and investigate possible venues...
