He has talked about it a few times over the years in interviews I've heard. He was a Woodville supporter as a kid because Les - or Bro as he was known, got involved with Woodville, even before its early days in the SANFL and McDermott was taken to home games by grandpa and he got to meet the players and they became his heroes. He has said he was shattered as a kid when he found out he couldn't play for them as he lived in the Glenelg zone - don't know where, but he did go to Brighton High with Stephen Kernahan.
As my former Year-8 cricket coach at BHS, I've known Bone for quite a while. Asked him a couple of years ago how long it took him to stop barracking for Woodville after joining the Bays. Sheepishly, he said, "I never stopped. I hated playing against Woodville."
