Among those Rolling Thunder motorcyclists who took over Washington this Memorial Day weekend was one "True Blood" werewolf -- actor Robert Patrick, also known for his roles in "Terminator 2," "Gangster Squad" and "Identity Theft." Patrick, who plays Alcide's father, Jackson Herveaux on the hit HBO show, participated in the Rolling Thunder's Ride for Freedom. Afterward, Patrick made his annual trek to Shelly's Back Room in downtown D.C., where he enjoyed a salad and iced tea, while smoking his own stogies.
