San Diego Padres vs San Francisco Giants
Fans celebrate after Giants 1B Travis Ishikawa's 2-out single loads the bases in the bottom of the 8th inning during a 2-1 win over the Padres on July 11, 2009, at AT&T Park in San Francisco. A rainbow was visible in the sky from 8:00pm to 8:38pm.
I've never seen a rainbow last for anywhere near that long. I was very busy shooting it and pretty much ignored the last 2 1/2 innings.
