Volunteers prepare for Special Olympics Duck Dash Sunday in Riviera Beach

RIVIERA BEACH, Fla. —

Volunteers tagged 5,000 rubber ducks Friday in preparation for the race at the Rapids Water Park in Riviera Beach Sunday.

The proceeds go to the Special Olympics of Palm Beach County.

"Special Olympics is always more important to me, because I do tennis, bowling, swimming and I did all four sports," said Brad Davis, the ambassador of Special Olympics Palm Beach County. "That’s why I’m always involved in Special Olympics over like 30 years."
