— Robert Patrick dropping by Shelley’s Backroom over Memorial Day weekend. When, exactly? Oh, Friday, Saturday, Sunday — the downtown cigar bar is a favorite, apparently. The tough guy actor (you know him from “Terminator 2,” “Gangster Squad,” a million other things) rolled into town with the annual Rolling Thunder motorcycle ride for POWs and MIAs. Beard, thick glasses, knit cap, biker gear.
