Roy is remembered by the off-road community as a true champion and leader. He worked and lobbied tirelessly to preserve public lands for OHV access until his passing in 2009. Denner founded the Off-Road Business Association (ORBA), a nationwide, non-profit trade association dedicated to this mission. Prior to starting ORBA, Roy became active in land-use in the 90’s as a member of the San Diego Off-Road Coalition, where he was the Director of Land Use.
