"I appreciate the opportunity I had to be on the AMA Board of Directors, and I have confidence in the direction the AMA is going as an organization," Cabral said. "I am going to miss my working relationship that I have developed with the AMA board. I have found it increasingly difficult to perform my duties as an AMA board member while also being the chairman of California's Off-Highway Motor Vehicle Recreation commission. California State Parks is going through a transformation process that requires an incredible amount of dedication and focus going forward. With that, I think it would better serve the AMA if I step down from my position on the AMA board."
