Rainbow at morning...balloonists take warning. The low, morning sun erupts briefly out of a break in cloud cover Saturday, May 15, 2011 shortly before 6 a.m. in Walla Walla, Wash. to illuminate a rainbow through damp skies above the Fairgrounds and launching point to the 37th Walla Walla Balloon Stampede. Citing "intermittent rain, instability and chances of thunder storms", balloonmeister Jerry Cummins closed the field to balloon launches shortly after the Pilots Meeting that morning.
