In January, a group of wildlife conservationists camped at the southern tip of the Everglades, ready to take the first step in a thousand-mile journey up the central spine of Florida. And they did it for 100 days straight - through swamps, cattle pasture and subdivisions on the creeping edge of suburbia. Why would they do that? Their mission: publicizing the need to connect the state's disjointed natural areas into a continuous wildlife corridor - from the Everglades to Georgia. They paddled through the Everglades, crossed through the heart of Florida's cattle country and pushed up the Kissimmee River valley into north Florida, ending 100 days later in the Okefenokee Swamp, just over the Georgia state line.
