"It couldn't be better. It's an amazing city and such an amazing parade to have in a city like this. Everything is going brilliant and the rain is staying away!" said one proud father, whose daughter was in the parade.
There was also a moving moment, when Consul General Philip Grant marched alongside first responders of the Berkeley balcony collapse that killed a group of Irish students.
"They're amazing men and women. They have great courage and great sympathy and understanding and have been by our side ever since," said Grant.

Many were seen catching beads and candy that were being tossed from floats. Over a 150 groups of dancers, policemen, firefighters, unions and marching bands took part.
The event was organized by the United Irish Society. This year marks the parade and festival's 165th anniversary. It's one of the largest Irish celebrations on the West Coast.
Perhaps it was the luck of the Irish that rain stayed away for almost the entire parade
