Members of the Florida Wildlife Corridor Expedition sport calluses and legs hardened by three months of hiking through sawgrass, palmetto stands and piney woods. They risked their lives walking across two Interstates.

Sunday, these four adventurers mark the end of a 1,000-mile trek across Florida: from the tip of the Everglades to the Okefenokee Swamp.

That might have been the easy part. Their next goal is to create a continuous corridor for wildlife running the length of the state. By documenting their journey, they hope to draw attention to the shrinking habitats and remind Floridians of their connection to the environment.

On a recent morning at Hopkins Prairie campground, deep in the Ocala National Forest, the day is greeted with the sounds of sandhill cranes taking flight.

As the sun rises through the fog, Carlton Ward Jr. takes it all in.

"I try not to miss a sunrise, if I can help it," he says.

Ward, the expedition leader, has his camera and is trying to get just that right shot.
