KEY BISCAYNE, Fla. -- Four Cuban migrants arrived at Bill Baggs Cape Florida State Park about 2:30 a.m. Tuesday, and another two were found sometime before 7 a.m. at a tollbooth about a mile away.

The U.S. Coast Guard spotted a 30-foot go-fast boat in the water, but the migrants made it ashore before the Coast Guard could intercept them.

The four men were treated for dehydration at the park but were expected to be OK.

"It was a hard, rough trip," said migrant Alesandro Gonzalez in Spanish. "We were really scared. There were sharks in the water. It was emotional. We cried. We prayed to God to make it so I could be with my family in Louisiana. My mom's sick and I'm going to work to help them out."

Another man said he has a girlfriend he hopes to propose to in the Carolinas, and another man said he has family in Miami.

A few hours later, a male and female migrant appeared on Key Biscayne. It was unclear if they came to shore on the same boat.
