Thousands of people began staking out prime spots on Colorado Boulevard. Most were equipped with folding chairs, tents, board games, sleeping bags and some even brought out barbecue grills.
"I don't think you'll find floats any better than the Rose Parade, anywhere in the country," said Florida resident Richard Wigglesworth, who was decked out in Wisconsin gear in support of his team playing Oregon at the Rose Bowl.
In all, 700,000 people are expected to attend the event.
Volunteers finished decorating the floats Sunday morning and the judges went by the warehouses to inspect them.
The gigantic floats were then moved to the route, from Irwindale to Pasadena, 19 miles at 3 mph. It was an arduous undertaking that took hours to complete so the flowers wouldn't be damaged.
"Going slower is faster," said Tim Estes, a volunteer for the Fiesta Parade float.
