Downtown Sacramento was a blur of baby blue T-shirts Saturday during the 2nd Annual Race for the Rock. More than 250 two-member teams competed for bling in the scavenger hunt, in which clues were sent via text message. The grand prize was a $20,000 Hearts on Fire diamond ring donated by Rogers Jewelry. Proceeds benefited Sacramento Food Bank and Family Services (SFBFS).

Unlike many other nonprofit fund raisers, donors got the ball rolling, not the charity.

"We wanted to do something that brought the community together and where people could have a good time," said Calvin Curtin of Rogers Jewelry. After deciding to do a scavenger hunt, Rogers chose SFBFS as its community partner.

"We told them we would put up all the money and prizes if they help us with the logistics," said Curtin. "(SFBFS) provided the volunteers. They are the ones who really stepped up to the plate."

Participants ran, biked and roller-bladed through the Grid. Obviously, speed was key, but knowledge of Sacramento landmarks and monuments also was vital. Bernadette Behar and Sue Dwyer-Voss discussed their strategy before the race began.

"I do a lot of urban walking," Behar said, "and I'm armed with a tour book of downtown."

The event kicked off at 10 a.m. on the west steps of the Capitol, with Mayor Kevin Johnson sending the first text message. Within two minutes, the plaza was empty. Checkpoints along the way included the Crest Theatre and the Convention Center.

It was all over by noon, with participants gathered on the patio of House Restaurant for lunch and the awards ceremony. The Detours, a local band, entertained the crowd with its mix of country and rock.

In keeping with the competition's text-messaged clues, that's how winners were contacted. Participants anxiously watched their cell phones for the announcement. The winners of the diamond ring were friends Andy and Steven.

Asked how he felt, Steven said, "I can't describe it," as he shook with excitement. The team said they would sell the ring.

Other prizes included diamond earrings, a diamond necklace, watches, bikes, gift cards and a GPS for a bike.

Kelly Siefkin of SFBFS summed up the day.

"It's a unique opportunity to spread the word about different organizations and businesses," she said. "And it's really fun."
