While beating my brains out trying to get more GOs, I came by a very few of these. They probably aren't worth anything, either. Every lady bowler that comes to town gets a certificate good for one of these. When I've tried to buy one at the cage, I've been told they are reserved for lady bowlers. When I said *I* was a lady bowler, I was asked for my certificate. Maybe after the WIBC is over more will be available. Maybe not. Sorry, I'm not giving any away just because somebody else has decided I "owe" them.
