The seniors were awarded possession of Hayden High School's spirit stick at a pep rally after the homecoming parade Friday afternoon, bringing an end to a week of class competition.
Seniors clinched the victory with their win for best float, despite wind trouble with their decorations that required a quick redesign before the parade.
The two secret float judges were looking for overall effort, enthusiasm and quality, said art teacher Susan Koehler, co-sponsor of the school's student council.
Students were engaged in class competition for Hayden's spirit stick throughout homecoming week, earning points for participating in dress-up days and lunchtime activities.
During the parade, class floats and homecoming royalty rolled by on Jefferson Avenue, along with the school band, playing Hayden High School's fight song.
Hayden High School alumni and longtime Hayden Tigers supporters Judy and Duane Hockett served as the grand marshals.
Senior parents being towed in a boat, toting signs such as "Sink the Rams," and students from Hayden Valley Elementary School, sporting orange and black and performing Tiger cheers, brought up the rear.
Several floats incorporated the "Pain Train" theme. The sophomore class float also featured a dead lamb constructed out of sheepskin, its eyes crossed over with tape, symbolizing defeat of the Soroco Rams at the homecoming game Friday night, sophomore Mackenzi Frick said.
Before the parade, Hayden High School senior Jade Stees had no doubt that their float would take the top prize.
"Our class is pretty loud," Stees said. "We're pretty spirited."
