My friend and Seattle radio legend Pat O’Day takes center stage for the 42nd year at Seafair this weekend… along with the fastest powerboats in the world, the Unlimited Hydroplanes. There’s action in the air too: the U.S. Navy Blue Angels return to thrill crowds Saturday at 1:30pm. KIRO TV will air more than six hours of live HD television coverage on Sunday starting at 10am.
