It's hot out. The usual midday thunderstorm has just passed, and the few kids hanging out on bleachers around the pool at Miami's Ransom Everglades School finally get the go-ahead to jump in and cool off.
Eight-year-old Gary Kendrick and the others are all here for swim lessons.
"They told us to hold on to the wall and kick our feet and, like, move our arms," Kendrick says. "When I had to swim to one of the counselors, I was really swimming. I ain't even know I was moving."
