SILVERDALE -- Kayleigh Perkins won't have a perfect season after placing second Sunday at the Silverdale Thunder 2009 race for unlimited lights.

Here are two views of the flip of the U-7 Graham Trucking during Sunday's unlimited hydroplane races on the Columbia River in Kennewick, Wash. These were posted on YouTube.

Steve David gave Art Oberto a victory at Seafair two years ago for his 80th birthday present.

Desiree Cameron cried Sunday looking at the makeshift memorial for her father in Columbia Park created by his boat-race buddies of more than 30 years.

By the time J. Michael Kelly knew he was going to flip over in the U-7 Graham Trucking on Sunday, he had the common sense to bring his body parts - his arms, his legs - as close to him as possible.

Kayleigh Perkins is still perfect in 2009.

If Sam Cole has his way, every unlimited racing team member will need to keep an active passport.

The U-3 Sun River Electric presents Grandview on the Lake had to withdraw from the race Sunday morning after a crack was found in the boat.

Steve David won his second consecutive Columbia Cup championship on Sunday, earning his fourth consecutive heat of the weekend on the banks of the Columbia River.
