like dude said. pop a pill and take him to a sideshow, a club wit some known bay rappers performing. take him to a rasputins and put him on some real bay rap not that hyphy shit he probably saw on MTV. Take him to telegraph blunted and laugh at the crazy muthafuckas there. Go to haight street.
How old is your cuzzin anyways? Depends on his age. If he's a kid or teenager, Great America and Six Flags is coo but not when your 28.
Go all out and rent a car. Drive to San Diego and work your way up back to the bay. Chill in SD for 2 days, Hollywood for 2 days, Vegas for a day, smoke a blunt at your house and chill for the last 2 days wit family.
