The story

When Doug Tompkins wants to drop in on his neighbor, the best way to do so -- in fact, the only way to do so -- is to fire up his Cessna 206 and fly across the vast subtropical wetlands that he owns in this remote corner of northeastern Argentina.

"I've been a pilot longer than you've been alive," says Tompkins, 66. And it's true.
