In 2018, Gannon told sports reporter Helen Ross that out of all the sports he has called, he found golf the hardest, even though he played it and had been a fan of the sport since childhood. He played golf in clubs near his home in Los Angeles, but most of his golf was played on the road, with former golf pros and fellow broadcasters like his Golf Channel broadcast partner, six-time major champion Nick Faldo, as well as with Craig Perks, Billy Kratzert, Matt Gogel, Jim Gallagher Jr., and Curt Byrum.
