GSD stands for Garry Scott Davis and he skated everyday. He invented the Boneless One with his friends, Robert Hamrick and Mark Mounts back in Ohio in 1980.
Here’s a sweet FS Boneless of Garry that I shot at the Shell Bowl in Oceanside in 1985. I worked with GSD for several years at TW and some of the funniest and most memorable experiences of my life somehow involved Garry.
