I was en route to meet Groot.
Not an imitation Groot conjured with video or those clunky virtual reality goggles. The Walt Disney Co.’s secretive research and development division, Imagineering, had promised a walking, talking, emoting Groot, as if the arboreal "Avengers” character had jumped off the screen and was living among us.
But first I had to find him. GPS had guided me to a warehouse on a dead-end street in Glendale, a Los Angeles suburb. The place seemed deserted. As soon as I parked, however, a man warily appeared from behind a jacaranda tree. Yes, I had an appointment. No, I was not hiding any recording devices. He made a phone call, and I was escorted into the warehouse through an unmarked door behind a dumpster.
