WINNEBAGO Cessna Caravan on floats an all-terrain RV ANYONE ELSE FLYING by might think the slash in the dirt is just a dusty path in the canyon, but it's a target for Wally Fisk as he wracks the Cessna Caravan on floats around and lines up for the mile-high strip. "Uphill, on a sideslope, with a dogleg in a box canyon," is how he describes the runway on his ranch in the Black Hills of South Dakota. "I probably have more landings on that runway than any other in the Caravan," he recalls. "It's a great backcountry airplane." BY THOMAS B.
