Authorities are expecting thousands of motorcyclists to descend on San Joaquin County today for the funeral of one of the founding members of the Oakland chapter of the Hells Angels Motorcycle Club and the international organization’s longtime de facto leader. And the San Joaquin County Sheriff said on Friday that his office has spent upwards of $500,000 to provide the manpower necessary for what law enforcement believes will be a massive turnout for the funeral of Ralph “Sonny” Barger Jr.
