COLUMBIA, Mo. (AP) _ Author William Least Heat-Moon, a k a Will Trogdon, is in a tiff with a boat operator after he crashed while being filmed by ``CBS Sunday Morning.''

Trogdon lost control of one boat on the Missouri River and rammed a second boat with the camera crew aboard last week.

``His boat starts swinging back and forth, he hits the throttle and lurches the boat forward into the back end of my boat, running up alongside and scraping the side,'' said Mike Ruh, who rented both boats to CBS for the interview.

Trogdon says the crash wasn't his fault. He says the other boat's wake broke the throttle and caused the boat to speed up.

``I am just an actor in this scene,'' he said.

Trogdon, who wrote ``Blue Highways'' has a new book due out Oct. 19 about exploring America's waterways. He says he was accident-free throughout the 5,300-mile voyage chronicled in ``River Horse.''
