Almost 6500 clover patches were found and searched during the course of the day on March 17th, but only these 18 had the Luck o' the Irish.
As a reward for their efforts and fortune, each winner was awarded 144 Pearls. (Why 144? Because this is Whyville's 12th birthday, so we took that number and squared it.)
Honorable Mention: stELtrain found the most clover patches of anyone on Whyville - 375! He, too, received the 144-Pearl prize.
