I didn't see a forum post for this tourney. Here is a link over to the pdga site with all the info. $7,000 added cash so far. Also, a fat players package for the Am's. And the payout scale will be one of the best around.
This is a direct quote from Jay "Yeti" Reading himself...
"Anyone who missed the Greatest Worlds of all-time, second chance on a smaller scale right here. Those that did make it, know and will be back."
