We could hear music and the popping of fireworks on the amusement pier and see rockets and star shells exploding above the line of old U.S. Army officers' quarters along the beachfront. A wave slid across my chest, and inside it I saw the pinkish blue air sac and long tendril-like stingers of a Portuguese man-of-war. It drifted away, then another one, and another fell out of a wave and twisted in an eddy like half-inflated balloons.

It was going to be a long haul to the beach.

"There's sharks in the water! Didn't you fellers see the lifeguard's flag?" a voice called.

I didn't know where the girl had come from. She sat astride an inner tube that was roped to two others, a short wood paddle in her hands. She wore a one-piece black swimsuit and had sandy reddish hair, and her shoulders glowed with sunburn. Behind her, in the distance, I could see the tip of a rock jetty that jutted far out into the breakers.

She paddled her makeshift raft until it had floated directly above the sandbar and we could wade to it.

"Where did you come from?" Jimmie said.

"Who cares? Better jump on. Those jellyfish can sting the daylights out of you" she said.

She was tall and slight of build and not much older than we were, her accent hardcore East Texas. A wave broke against my back, pushing me off balance. "Are you fellers deaf? Y'all sure don't act like you care somebody is trying to hep you out of the big mess you got yourself into," she said.

"We're coming!" Jimmie said, and climbed onto one of the inner tubes.

Waves knocked us over twice and it took us almost a half hour to cross the trough between the third and second sandbars. I thought I saw a fin break the surface and slide across the sun's afterglow, and, once, a hard-bodied object bumped against my leg, like a dull-witted bully pushing past you on a crowded bus. But after we floated past the second sandbar, we entered another environment, one connected to predictability where we could touch bottom with the ends of our toes and smell smoke from meat fires and hear children playing tag in the darkness.
