Marcos worked 25 years as a River Ranger for the Big Bend National Park Service. Now he's retired and runs a small aviation business. He lives in a beautiful home only a few miles from the border, where he never locks his car and doesn't even know where his house keys are.
"The Rio Grande is my whole life - it provided me a career, it put my kids through school, helped me build this house. It's my whole life. Without the river there would be far fewer folks around here."
"For some along it, the river provides water for agriculture, for others it provides water for recreation, but either way what it provides is life."
