Barnett got into whitewater paddling while at Vanderbilt and it changed his life. He has paddled some of the toughest rivers in the US and on 3 continents. He loved teaching others about his sport and taught 100s or 1000s of students over 40 years.
He also loved going out west in the summer to paddle and climb mountains and has climbed a dozen of fourteeners (14k') in Colorado and Italy.
Maryn loves that he has this hobby but doesn't join him because she does not voluntarily exert any unnecessary energy.
