South Florida residents who hail from the Caribbean are lauding their countries' London 2012 Olympic Games success this week.

From Jamaican Usain Bolt’s repeat as the world’s fastest man to Dominican Felix Sanchez’s win in the 400-meter men’s hurdles, Caribbean Olympic teams and their supporters have much to smile about.

Just ask Iveliss Rosario, who sells dishes from Puerto Rico and Cuba and has one parent from each nation. The U.S. native watches the islanders' success with special pride.

"I do feel that everything runs in my blood,” she said.

She watched Sanchez earn the Dominican Republic's first 2012 gold in the 400-meter hurdles. The 34-year-old did it in memory of his grandmother. A Puerto Rican competitor took home bronze.

"To me they're taking it very personal, especially for their country,” Rosario said.

Meantime, Cuban natives revel in victories like that of wrestler Mijain Lopez, who scored gold at 120 kilograms Monday night.

And the island of Grenada even declared Tuesday afternoon a holiday to mark its first-ever gold medal, for Kirani James’ victory in the 400 meters.

Two-time 100-meter gold medalist Bolt topped his heat Tuesday morning in the 200-meter race. He'll compete in that final Wednesday.

"Oh forget it – there's nobody that could beat him right now,” Rosario said.
