The Green Lake Milk Carton Derby kicked off Seafair 2006 on July 1 with a full day of family activities enjoyed by an estimated 20,000 people. It was a fun-filled day for the whole family. Visitors squealed at the spectacular lunchtime entertainment provided by the Valentines Performing Pigs. 70 boaters competed to try and win a share of the $10,000 prize money. Seafair Pirates put in an appearance, too. See the Seafair web site for more. Water quality is key to the enjoyment of Green Lake’s popular activities, and the water is clean and clear, thank’s to last year’s alum treatment.
