"We're kind of stereotyped as these big monsters, and we're not," he said. "I don't know why we're so misunderstood down there in the Twin Cities area because I believe we're the true stewards of the land."

He says trees are like people.
"When you get to 80, you become more susceptible to diseases, you're on the downward slide and you die. Same thing with wood."
Last fall, Rolle was invited to a meeting at a logging industry seminar in Tower. Unlike previous years, the Forest Resources Association didn't tip off the winner of its Outstanding Logger from the region. When they announced his name, he turned to Mike Anderson, who's been his so-called delimber for 25 years.
